Currently TCP ports like NFS lock manager are not tracked. It is
easier to track all connections than to add a configuration system to
try to track specified ports, so do that.

Running ss to get current connections before running ctdb gettickles
means the ss output might be out of date when the 2 lists are
compared. Some tickles might have been added after ss was run by some
other means (e.g. SMB tickles, added internally) and they would be
deleted according to the stale ss output.
This isn't currently a problem because update_tickles() is currently
only called with port 2049, so all tickles are managed by this code.
That will change in a subsequent commit.
Changing the order means the reverse problem can occur, where
update_tickles() attempts to delete an already deleted tickle. That
may happen occasionally but is harmless because it doesn't result in
missing information. It (currently) just causes a message to be
logged at DEBUG level.

(cherry picked from commit b3e2c69ad9)
With an empty IP filter, all incoming connections to port 2049 will be
listed, not just those to public IP addresses. This causes error
messages like the following to be logged:
ctdb-eventd[...]: 60.nfs: Failed to add 1 tickles
since the connection being added seems to be for a random NFS mount
that doesn't use a public IP addresses.
This has been a problem for a long time (probably since commit
04fe9e2074 in 2015). It isn't currently
a huge deal because it only affects NFS connections. However, this
code will soon be used to track connections to public IP addresses on
all ports. This would result in a constant stream of log messages,
since there will always be some active connections.
The theory behind the fix is that if a node hosts no public IPs then
it should have no relevant connections and has no business changing
the list of registered tickles.
