If site replication enabled across sites, replicate the SSE-C
objects as well. These objects could be read from target sites
using the same client encryption keys.

As total drives count, online vs offline are per node basis, its
corect to select node for which graphs need to be rendered.
Set prometheus scrape jobs to fetch metrics from all nodes. A sample
scrape job for node metrics could be as below
```
- job_name: minio-job-node
bearer_token: <token>
metrics_path: /minio/v2/metrics/node
scheme: https
tls_config:
insecure_skip_verify: true
static_configs:
- targets: [tenant1-ss-0-0.tenant1-hl.tenant-ns.svc.cluster.local:9000,tenant1-ss-0-1.tenant1-hl.tenant-ns.svc.cluster.local:9000,tenant1-ss-0-2.tenant1-hl.tenant-ns.svc.cluster.local:9000,tenant1-ss-0-3.tenant1-hl.tenant-ns.svc.cluster.local:9000]

Metrics v3 is mainly a reorganization of metrics into smaller groups of
metrics and the removal of internal aggregation of metrics received from
peer nodes in a MinIO cluster.
This change adds the endpoint `/minio/metrics/v3` as the top-level metrics
endpoint and under this, various sub-endpoints are implemented. These
are currently documented in `docs/metrics/v3.md`
The handler will serve metrics at any path
`/minio/metrics/v3/PATH`, as follows:
when PATH is a sub-endpoint listed above => serves the group of
metrics under that path; or when PATH is a (non-empty) parent
directory of the sub-endpoints listed above => serves metrics
from each child sub-endpoint of PATH. otherwise, returns a no
resource found error
All available metrics are listed in the `docs/metrics/v3.md`. More will
be added subsequently.
there can be a sudden spike in tiny allocations,
due to too much auditing being done, also don't hang
on the
```
h.logCh <- entry
```
after initializing workers if you do not have a way to
dequeue for some reason.
The middleware sets up tracing, throttling, gzipped responses and
collecting API stats.
Additionally, this change updates the names of handler functions in
metric labels to be the same as the name derived from Go lang reflection
on the handler name.
The metric api labels are now stored in memory the same as the handler
name - they will be camelcased, e.g. `GetObject` instead of `getobject`.
For compatibility, we lowercase the metric api label values when emitting the metrics.
Moved different dashboards to their specific directories. Also
mentioned that these dashbards are examples of how to create
graphs using MinIO provided and metrics and customers should
change / add graphs on their specific need basis.

This change is to decouple need for root credentials to match between
site replication deployments.
Also ensuring site replication config initialization is re-tried until
it succeeds, this deoendency is critical to STS flow in site replication
scenario.
globalLocalDrives seem to be not updated during the
HealFormat() leads to a requirement where the server
needs to be restarted for the healing to continue.
