Currently, pool just returns an error with text message and without a node that returned that error.

I think it can:

Return node's endpoint via message;
Log errors with debug using internal logger;
...

Will simplify debug a little. E.g. in the morph multiclient I tried to log as much internal uncontrolable processes as I can.

Currently, pool just [returns](https://git.frostfs.info/TrueCloudLab/frostfs-sdk-go/src/commit/f41860f9bd41368d5ddedeb9ed535fcfe97c0fa3/pool/pool.go#L818) an error with text message and _without_ a node that returned that error. I think it can: 1. Return node's endpoint via message; 2. Log errors with `debug` using internal [logger](https://git.frostfs.info/TrueCloudLab/frostfs-sdk-go/src/commit/f41860f9bd41368d5ddedeb9ed535fcfe97c0fa3/pool/pool.go#L1563); 3. ... Will simplify debug a little.

Let's go further and add a metric that returns current endpoint pool is talking to.

We should also pass logger to the wrapper:

prm.logger = params.logger

or add methods to set logger and use it

We should also pass logger to the [wrapper](https://git.frostfs.info/TrueCloudLab/frostfs-sdk-go/src/commit/aa8ffebc632840847215a39bfe69d64ad9571bf6/pool/pool.go#L1746): ``` prm.logger = params.logger ``` or add methods to set logger and use it

Summary:

issue is related for object pool, not tree pool,
in case of the error, pool should wrap endpoint address of the storage node before passing error to the caller,
add a metric to provide endpoint of current storage node which pool is connected to,
provide a way to pass logger to the wrapper.

Summary: - issue is related for _object_ pool, not _tree_ pool, - in case of the error, `pool` should wrap endpoint address of the storage node before passing error to the caller, - add a [metric](https://git.frostfs.info/TrueCloudLab/frostfs-sdk-go/src/branch/master/pool/statistic.go) to provide endpoint of current storage node which `pool` is connected to, - provide a way to pass logger to the [wrapper](https://git.frostfs.info/TrueCloudLab/frostfs-sdk-go/src/commit/aa8ffebc632840847215a39bfe69d64ad9571bf6/pool/pool.go#L1746).

From my POV we should have 2 metrics:

first for storage pool: show current healthy endpoints with the same priority
second for tree pool: current connected endpoint

From my POV we should have 2 metrics: - first for storage pool: show current healthy endpoints with the same priority - second for tree pool: current connected endpoint
