[PATCH] ctdb-scripts: Use ss instead of netstat for finding TCP connections

[Martin Schwenke]

ss with a filter is much faster than post-processing output from
netstat.  CTDB already has a hard dependency on iproute2 for IP
address handling, so depending on ss is no big deal.

Note that there are other bottlenecks, such as connecting to ctdbd to
register individual tickles...  those are coming soon.

Please review and maybe push...

peace & happiness,
martin
