> When a CSI plugin crashes, the container daemon in SLRP will reset its corresponding {{csi::Client}} service future. However, if a CSI call races with a plugin crash, the call may be issued before the service future is reset, resulting in a failure for that CSI call. MESOS-9517 partly addresses this for {{CreateVolume}} and {{DeleteVolume}} calls, but calls in the SLRP recovery path, e.g., {{ListVolume}}, {{GetCapacity}}, {{Probe}}, could make the SLRP unrecoverable.
> There are two main issues:
>  1. For {{Probe}}, we should investigate if it is needed to make a few retry attempts, then after that, we should recover from failed attempts (e.g., kill the plugin container), then make the container daemon relaunch the plugin instead of failing the daemon.
> 2. For other calls in the recovery path, we should either retry the call, or make the local resource provider daemon be able to restart the SLRP after it fails.
