Allow for configurability of NFS values
Customer is using the Tile and attempting to backup their repositories. However, it seems that there are random failures, possibly due to NFS timeouts.
@WarheadsSE noticed the timeo and rpc.nfsd options are different with GitLab.com.
Distinct points:
runbook mount: defaults,soft,rsize=1048576,wsize=1048576,timeo=50,noatime,lookupcache=positive
Tile mount: timeo=10,intr,lookupcache=positive
runbook rpc.nfsd proc: 50
tile rpc.nfsd proc: 8
