ctdb-scripts: Switch NFS checks to new style Note that the 60.ganesha RPC checks need to be identical to those in the nfs-checks.d/ directory. This is because the NFS unit test infrastructure checks output against what should be produced by the checks in nfs-checks.d/. This is a minor issue, since one of the aims of this work is to remove the need for a separate 60.ganesha. In most cases configuration variable CTDB_NFS_DUMP_STUCK_THREADS is now ignored. This is now handled by passing the desired number of threads to the command specified in the service_debug_cmd variable in a .check file.

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

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()
