currently getReplicationConfig() failure incorrectly
returns error on unexpected buckets upon upgrade, we
should always calculate usage as much as possible.
listing can fail and it is allowed to be retried,
instead of returning right away return an error at
the end - heal the rest of the buckets and objects,
and when we are retrying skip the buckets that
are already marked done by using the tracked buckets.

- Go might reset the internal http.ResponseWriter() to `nil`
after Write() failure if the go-routine has returned, do not
flush() such scenarios and avoid spurious flushes() as
returning handlers always flush.
- fix some racy tests with the console
- avoid ticker leaks in certain situations
Existing:
```go
type xlMetaV2 struct {
Versions []xlMetaV2Version `json:"Versions" msg:"Versions"`
}
```
Serialized as regular MessagePack.
```go
//msgp:tuple xlMetaV2VersionHeader
type xlMetaV2VersionHeader struct {
VersionID [16]byte
ModTime int64
Type VersionType
Flags xlFlags
}
```
Serialize as streaming MessagePack, format:
```
int(headerVersion)
int(xlmetaVersion)
int(nVersions)
for each version {
binary blob, xlMetaV2VersionHeader, serialized
binary blob, xlMetaV2Version, serialized.
}
```
xlMetaV2VersionHeader is <= 30 bytes serialized. Deserialized struct
can easily be reused and does not contain pointers, so efficient as a
slice (single allocation)
This allows quickly parsing everything as slices of bytes (no copy).
Versions are always *saved* sorted by modTime, newest *first*.
No more need to sort on load.
* Allows checking if a version exists.
* Allows reading single version without unmarshal all.
* Allows reading latest version of type without unmarshal all.
* Allows reading latest version without unmarshal of all.
* Allows checking if the latest is deleteMarker by reading first entry.
* Allows adding/updating/deleting a version with only header deserialization.
* Reduces allocations on conversion to FileInfo(s).
This will help other projects like `health-analyzer` to verify that the
struct was indeed populated by the minio server, and is not
default-populated during unmarshalling of the JSON.

legacy objects in 'xl.json' after upgrade, should have
following sequence of events - bucket should have versioning
enabled and the object should have been overwritten with
another version of an object.
this situation was not handled, which would lead to older
objects to stay perpetually with "legacy" dataDir, however
these objects were readable by all means - there weren't
converted to newer format.
This PR fixes this situation properly.
Add a new Prometheus metric for bucket replication latency
e.g.:
minio_bucket_replication_latency_ns{
bucket="testbucket",
operation="upload",
range="LESS_THAN_1_MiB",
server="127.0.0.1:9001",
targetArn="arn:minio:replication::45da043c-14f5-4da4-9316-aba5f77bf730:testbucket"} 2.2015663e+07

container limits would not be properly honored in
our current implementation, mem.VirtualMemory()
function only reads /proc/meminfo which points to
the host system information inside the container.
This feature is useful in situations when console is exposed
over multiple intranent or internet entities when users are
connecting over local IP v/s going through load balancer.

- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed

- add checks such that swapped disks are detected
and ignored - never used for normal operations.
- implement `unrecognizedDisk` to be ignored with
all operations returning `errDiskNotFound`.
- also add checks such that we do not load unexpected
disks while connecting automatically.
- additionally humanize the values when printing the errors.
Bonus: fixes handling of non-quorum situations in
getLatestFileInfo(), that does not work when 2 drives
are down, currently this function would return errors
incorrectly.
creating service accounts is implicitly enabled
for all users, this PR however adds support to
reject creating service accounts, with an explicit
"Deny" policy.
On first list resume or when specifying a custom markers entries could be missed in rare cases.
Do conservative truncation of entries when forwarding.

If a given MinIO config is dynamic (can be changed without restart),
ensure that it can be reset also without restart.
