When an NFS check restarts a failed service by hand then systemd will be unable to stop or start this service again because (at least) the PID file will be wrong. Do this via the NFS Linux kernel call-out instead. Allow the call-out to use the services instead of doing manual restarts. Add variables for mount, status and rquotad services to support this. Adding systemd NFS services to the call-out will follow.

NFS check configuration files.
Files are named NN.RPCSERVICE.check. Files without a .check suffix
are ignored.
Supported variables are:
* family - "tcp" or "udp" or space separated list
default: tcp, not used with "service_check_cmd"
* version - optional, RPC service version number
default is to omit to check for any version,
not used with "service_check_cmd"
* unhealthy_after - number of check fails before unhealthy
default: 1
* restart_every - number of check fails before restart
default: 0, meaning no restart
* service_stop_cmd - command to stop service
default: no default, must be provided if
restart_every > 0
* service_start_cmd - command to start service
default: no default, must be provided if
restart_every > 0
* service_check_cmd - command to check health of service
default is to check RPC service using rpcinfo
* service_debug_cmd - command to debug a service after trying to stop it;
for example, it can be useful to print stack
traces of threads that have not exited, since
they may be stuck doing I/O;
no default, see also function program_stack_traces()
Quoting inside values is not preserved.
