"Node not found for partition <namespace>:<some_number> in partition table" error when using a closed client

[marius-nicolae]

If by mistake a client is closed "too early", and still used afterward, a "Node not found for partition : in partition table" error is returned. To save troubleshooting time, in such a case, a specific error should be returned (ex. "Closed client usage attempt", or something similar) instead of a cryptic and misleading error, as described above!

This is not a good idea. We cannot put a mutex for every request. That would create a huge contention.
