Remove MaxConnsPerHost settings to avoid potential hangs (#10438)
MaxConnsPerHost can potentially hang a call without any
way to timeout, we do not need this setting for our proxy
and gateway implementations instead IdleConn settings are
good enough.

Also ensure to use NewRequestWithContext and make sure to
take the disks offline only for network errors.

Fixes #10304

certs: refactor cert manager to support multiple certificates (#10207)
This commit refactors the certificate management implementation
in the `certs` package such that multiple certificates can be
specified at the same time. Therefore, the following layout of
the `certs/` directory is expected:
```
certs/
 │
 ├─ public.crt
 ├─ private.key
 ├─ CAs/          // CAs directory is ignored
 │   │
 │    ...
 │
 ├─ example.com/
 │   │
 │   ├─ public.crt
 │   └─ private.key
 └─ foobar.org/
     │
     ├─ public.crt
     └─ private.key
   ...
```

However, directory names like `example.com` are just for human
readability/organization and don't have any meaning w.r.t whether
a particular certificate is served or not. This decision is made based
on the SNI sent by the client and the SAN of the certificate.

***

The `Manager` will pick a certificate based on the client trying
to establish a TLS connection. In particular, it looks at the client
hello (i.e. SNI) to determine which host the client tries to access.
If the manager can find a certificate that matches the SNI it
returns this certificate to the client.

However, the client may choose to not send an SNI or tries to access
a server directly via IP (`https://<ip>:<port>`). In this case, we
cannot use the SNI to determine which certificate to serve. However,
we also should not pick "the first" certificate that would be accepted
by the client (based on crypto. parameters - like a signature algorithm)
because it may be an internal certificate that contains internal hostnames. 
We would disclose internal infrastructure details doing so.

Therefore, the `Manager` returns the "default" certificate when the
client does not specify an SNI. The default certificate the top-level
`public.crt` - i.e. `certs/public.crt`.

This approach has some consequences:
 - It's the operator's responsibility to ensure that the top-level
   `public.crt` does not disclose any information (i.e. hostnames)
   that are not publicly visible. However, this was the case in the
   past already.
 - Any other `public.crt` - except for the top-level one - must not
   contain any IP SAN. The reason for this restriction is that the
   Manager cannot match a SNI to an IP b/c the SNI is the server host
   name. The entire purpose of SNI is to indicate which host the client
   tries to connect to when multiple hosts run on the same IP. So, a
   client will not set the SNI to an IP.
   If we would allow IP SANs in a lower-level `public.crt` a user would
   expect that it is possible to connect to MinIO directly via IP address
   and that the MinIO server would pick "the right" certificate. However,
   the MinIO server cannot determine which certificate to serve, and
   therefore always picks the "default" one. This may lead to all sorts
   of confusing errors like:
   "It works if I use `https:instance.minio.local` but not when I use
   `https://10.0.2.1`.

These consequences/limitations should be pointed out / explained in our
docs in an appropriate way. However, the support for multiple
certificates should not have any impact on how deployment with a single
certificate function today.

Cluster healthcheck improvements (#10408)
- do not fail the healthcheck if heal status
  was not obtained from one of the nodes,
  if many nodes fail then report this as a
  catastrophic error.
- add "x-minio-write-quorum" value to match
  the write tolerance supported by server.
- admin info now states if a drive is healing
  where madmin.Disk.Healing is set to true
  and madmin.Disk.State is "ok"

crypto: allow multiple KES endpoints (#10383)
This commit addresses a maintenance / automation problem when MinIO-KES
is deployed on bare-metal. In orchestrated env. the orchestrator (K8S)
will make sure that `n` KES servers (IPs) are available via the same DNS
name. There it is sufficient to provide just one endpoint.

getDisksInfo: Attribute failed disks to correct endpoint (#10360)
If DiskInfo calls failed the information returned was used anyway 
resulting in no endpoint being set.

This would make the drive be attributed to the local system since 
`disk.Endpoint == disk.DrivePath` in that case.

Instead, if the call fails record the endpoint and the error only.

use single dynamic timeout for most locked API/heal ops (#10275)
newDynamicTimeout should be allocated once, in-case
of temporary locks in config and IAM we should
have allocated timeout once before the `for loop`

This PR doesn't fix any issue as such, but provides
enough dynamism for the timeout as per expectation.

admin: new API for creating KMS master keys (#9982)
This commit adds a new admin API for creating master keys.
An admin client can send a POST request to:
```
/minio/admin/v3/kms/key/create?key-id=<keyID>
```

The name / ID of the new key is specified as request
query parameter `key-id=<ID>`.

Creating new master keys requires KES - it does not work with
the native Vault KMS (deprecated) nor with a static master key
(deprecated).

Further, this commit removes the `UpdateKey` method from the `KMS`
interface. This method is not needed and not used anymore.

support proper values for listMultipartUploads/listParts (#9970)
object KMS is configured with auto-encryption,
there were issues when using docker registry -
this has been left unnoticed for a while.

This PR fixes an issue with compatibility.

Additionally also fix the continuation-token implementation
infinite loop issue which was missed as part of #9939

Also fix the heal token to be generated as a client
facing value instead of what is remembered by the
server, this allows for the server to be stateless 
regarding the token's behavior.

Reroute requests based token heal/listing (#9939)
When manual healing is triggered, one node in a cluster will 
become the authority to heal. mc regularly sends new requests 
to fetch the status of the ongoing healing process, but a load 
balancer could land the healing request to a node that is not 
doing the healing request.

This PR will redirect a request to the node based on the node 
index found described as part of the client token. A similar
technique is also used to proxy ListObjectsV2 requests
by encoding this information in continuation-token

metrics: Use StorageInfo() instead to have consistent info (#9006)
Metrics used to have its own code to calculate offline disks.
StorageInfo() was avoided because it is an expensive operation
by sending calls to all nodes.

To make metrics & server info share the same code, a new
argument `local` is added to StorageInfo() so it will only
query local disks when needed.

Metrics now calls StorageInfo() as server info handler does
but with the local flag set to false.
