all retries must not be counted as failed messages,
a failed message is a single counter not for all
retries, this PR fixes this.
Also we do not need to retry 10-times, instead we should
retry at max 3 times with some jitter to deliver the
messages.
If MinIO started with KMS enabled, MINIO_KMS_KES_KEY_NAME should
be set for server to start.

In a perf test, one node will run speed test with all nodes. If there is
an error with a peer node, the peer node name is not included in the
error hence confusing the user.
This commit will add the peer endpoint string to the netperf error.
To ensure that policy mappings are current for service accounts
belonging to (non-derived) STS accounts (like an LDAP user's service
account) we periodically reload such mappings.
This is primarily to handle a case where a policy mapping update
notification is missed by a minio node. Such a node would continue to
have the stale mapping in memory because STS creds/mappings were never
periodically scanned from storage.
- we already have MRF for most recent failures
- we trigger healing during HEAD/GET operation
These are enough, also change the default max wait
from 5sec to 1sec for default scanner speed.
AccountInfo is quite frequently called by the Console UI
login attempts, when many users are logging in it is important
that we provide them with better responsiveness.
- ListBuckets information is cached every second
- Bucket usage info is cached for up to 10 seconds
- Prefix usage (optional) info is cached for up to 10 secs
Failure to update after cache expiration, would still
allow login which would end up providing information
previously cached.
This allows for seamless responsiveness for the Console UI
logins, and overall responsiveness on a heavily loaded
system.
From the Go specification:
"3. If the map is nil, the number of iterations is 0." [1]
Therefore, an additional nil check for before the loop is unnecessary.

- remove targetClient for passing around via replicationObjectInfo{}
- remove cloing to object info unnecessarily
- remove objectInfo from replicationObjectInfo{} (only require necessary fields)
When using a chain provider all providers do not return a valid
access and secret key, an anonymous request is sent, which makes it hard
for users to figure out what is going on
In the case of S3 tiering, when AWS IAM temporary account generation returns
an error, an anonymous login will be used because of the chain provider.
Avoid this and use the AWS IAM provider directly to get a good error
message.
This helps reduce disk operations as these periodic routines would not
run concurrently any more.
Also add expired STS purging periodic operation: Since we do not scan
the on-disk STS credentials (and instead only load them on-demand) a
separate routine is needed to purge expired credentials from storage.
Currently this runs about a quarter as often as IAM refresh.
Also fix a bug where with etcd, STS accounts could get loaded into the
iamUsersMap instead of the iamSTSAccountsMap.
This allows scanner to avoid lengthy scans, skip
things appropriately and also not lose metrics in
any manner.
reduce longer deadlines for usage-cache loads/saves
to match the disk timeout which is 2minutes now per
IOP.
In situations with large number of STS credentials on disk, IAM load
time is high. To mitigate this, STS accounts will now be loaded into
memory only on demand - i.e. when the credential is used.
In each IAM cache (re)load we skip loading STS credentials and STS
policy mappings into memory. Since STS accounts only expire and cannot
be deleted, there is no risk of invalid credentials being reused,
because credential validity is checked when it is used.
Currently we have IOPs of these patterns
```
[OS] os.Mkdir play.min.io:9000 /disk1 2.718µs
[OS] os.Mkdir play.min.io:9000 /disk1/data 2.406µs
[OS] os.Mkdir play.min.io:9000 /disk1/data/.minio.sys 4.068µs
[OS] os.Mkdir play.min.io:9000 /disk1/data/.minio.sys/tmp 2.843µs
[OS] os.Mkdir play.min.io:9000 /disk1/data/.minio.sys/tmp/d89c8ceb-f8d1-4cc6-b483-280f87c4719f 20.152µs
```
It can be seen that we can save quite Nx levels such as
if your drive is mounted at `/disk1/minio` you can simply
skip sending an `Mkdir /disk1/` and `Mkdir /disk1/minio`.
Since they are expected to exist already, this PR adds a way
for us to ignore all paths upto the mount or a directory which
ever has been provided to MinIO setup.
Previously existing objects were queued to single worker and MRF re-queues
are also handled by same worker - this does not fully use the available
bandwidth in case there is no incoming workload.
Errors such as
```
returned an error (context deadline exceeded) (*fmt.wrapError)
```
```
(msgp: too few bytes left to read object) (*fmt.wrapError)
```
configs from 2020 server throws an
error due to deprecation of the keys
however an attempt is made to parse
them, we should have chosen existing
defaults - this PR fixes that.
