ctdb-scripts: Protect against races when starting grace period
While the PID check is worth it in relevant cases, NFS-Ganesha still
might go away after the check. Unfortunately, neither grace command
fails an indicative exit code, so invent one by checking error
messages. This can then be converted to success by the caller.

ctdb-scripts: Check NFS-Ganesha is running before attempting grace
If monitoring has failed because it isn't running, then don't fail
"startipreallocate" or "relaseip" by trying to go into grace.
Don't check this for "takeip". In that case NFS-Ganesha had better be
running.

ctdb-scripts: Improve NFS-Ganesha export path extraction
Path values do not need to have quotes. The current code fails if
there aren't any.
Instead, implement a 2 stage parser using 2 sed commands. See
comments in the code for details.
Regexps are POSIX basic regular expressions, apart from \<WORD\> (used
to ensure WORD is on word boundaries, and the 'i' flag for case
insensitivity. The latter is supported in FreeBSD sed.
This code successfully parses Path values out of the following
monstrosity:
path = "/foo/bar1;a";
Path = /foo/bar2;
Something = false;
Pseudo = "/foo/bar3x" ; Path = "/foo/bar3; y" ; Access_type = RO;
Pseudo = "/foo/bar4x" ; path=/foo/bar4; Access_type = RO;
Pseudo = "/foo/barNONONO" ; not_Path=/foo/barNONONO; Access_type = RO;
Path = /foo/bar5
Pseudo = "/foo/bar6x Path=foo" ; Path=/foo/bar6; Access_type = RO
This is probably the best that can be done within a shell script.

ctdb-scripts: Set ownership of statd-callout state directory
For add-client and del-client, statd-callout is called by rpc.statd,
which runs as rpcuser, statd or some other non-root system user. This
means that add-client and del-client can't write in the statd-callout
state directory if it is only writable by root. rpc.statd must be
able to write to its own local system statd state directory, so find
this directory and use it as a reference to set the ownership of
CTDB's statd-callout state directory.

ctdb-scripts: Avoid connecting to ctdbd in add-client/del-client
rpc.statd runs statd-callout as a non-root user, which is currently
hacked around using some sudo logic that fails to work in some
contexts (e.g. in a container).
Use $CTDB_MY_PUBLIC_IPS_CACHE to access the node's currently assigned
public IPs, for add-client/del-client. This avoids connecting to
ctdbd when called from rpc.statd.
Also, use $CTDB_MY_PUBLIC_IPS_CACHE in other places where it makes
sense.
Connections to ctdbd are still made in the "notify" action, but this
is always run as root.
In the test code, set the PNN after public addresses setup so that the
cache of assigned IPs correctly initialised.

ctdb-scripts: Add caching function for public IPs
This is way more complicated than I would like but, as per the
comment, this is due to complexities in the way public IPs work. The
main consumer will be statd-callout, which will then be able to run as
a non-root user.
Also generate the cache file in test code, whenever the PNN is set.
However, this can cause "ctdb ip" to generate a fake IP layout before
public IPs are setup. So, have the "ctdb ip" stub generate the IP
layout every time it is run to avoid it being stale.
