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.

fix: re-use connections in webhook/elasticsearch (#9461)
- elasticsearch client should rely on the SDK helpers
  instead of pure HTTP calls.
- webhook shouldn't need to check for IsActive() for
  all notifications, failure should be delayed.
- Remove DialHTTP as its never used properly

fix: fetchLambdaInfo should return consistent results (#9332)
- Introduced a function `FetchRegisteredTargets` which will return
  a complete set of registered targets irrespective to their states,
  if the `returnOnTargetError` flag is set to `False`
- Refactor NewTarget functions to return non-nil targets
- Refactor GetARNList() to return a complete list of configured targets

Use user CAs in checkEndpoint() call (#8911)
The server info handler makes a http connection to other
nodes to check if they are up but does not load the custom
CAs in ~/.minio/certs/CAs.

This commit fix it.

Harshavardhana 9e7a3e6adc Extend further validation of config values (#8469)
- This PR allows config KVS to be validated properly
  without being affected by ENV overrides, rejects
  invalid values during set operation

- Expands unit tests and refactors the error handling
  for notification targets, returns error instead of
  ignoring targets for invalid KVS

- Does all the prep-work for implementing safe-mode
  style operation for MinIO server, introduces a new
  global variable to toggle safe mode based operations
  NOTE: this PR itself doesn't provide safe mode operations

Drain response body properly for http connection pool (#6415)
Currently Go http connection pool was not being properly
utilized leading to degrading performance as the number
