> Handle plugin crashes gracefully in SLRP recovery.

>             Project: Mesos
>          Issue Type: Improvement
>            Reporter: Chun-Hung Hsiao
>            Assignee: Benjamin Bannier

> 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.
