Add per connection RPC metrics (#19852) 
Provides individual and aggregate stats for each RPC connection.

Example:

```
  "rpc": {
   "collectedAt": "2024-05-31T14:33:29.1373103+02:00",
   "connected": 30,
   "disconnected": 0,
   "outgoingStreams": 69,
   "incomingStreams": 0,
   "outgoingBytes": 174822796,
   "incomingBytes": 175821566,

Read drive IO stats from sysfs instead of procfs (#19131) 
Currently, we read from `/proc/diskstats` which is found to be
un-reliable in k8s environments. We can read from `sysfs` instead.

Also, cache the latest drive io stats to find the diff and update
the metrics.

Capture percentage of cpu load and memory used (#18596) 
By default the cpu load is the cumulative of all cores. Capture the
percentage load (load * 100 / cpu-count)

Also capture the percentage memory used (used * 100 / total)

Use better host names for metric errors (#18188) 
Typically hosts would end up like this:

```
   "hosts": [
        ":9000",
        ":9000",
        ":9000",
...
```

Also add host name to errors.

Add support for resource metrics (#18057) 
Add a new endpoint for "resource" metrics `/v2/metrics/resource`

This should return system metrics related to drives, network, CPU and
memory. Except for drives, other metrics should have corresponding "avg"
and "max" values also.

Reuse the real-time feature to capture the required data,
introducing CPU and memory metrics in it.

Collect the data every minute and keep updating the average and max values
accordingly, returning the latest values when the API is called.
