When thousands of connections are being killed the logs are flooded
with information about connections that should be killed. When some
connections are not killed then the number not killed is printed.
This is the wrong way around! When debugging "fail-back" problems, it
is important to know details of connections that were *not* killed.
It is almost never important to know the full list of all connections
that were *supposed* to be killed.
Instead, print a summary showing how many connections of the total
were killed. If any were not killed then print a list of remaining
connections.
Update unit tests: infrastructure for fake TCP connections, existing,
test cases, add new test cases.

Commit 86792724a2 added complications on
top of the multiple TCP port checking methods that used to exist.
Life is simpler now and the cause of any failures is obvious. So just
print a simple message if the port check fails.
Tweak tests to match changes. Drop one test that becomes a duplicate.
Temporarily tweak ctdb_check_command() so that it passes shellcheck
tests. It will be removed anyway in a subsequent commit.

This has bit-rotted, at least for NFS. It can be fixed but it is
better to remove it because it adds a lot of unnecessary complexity.
Variable event_name becomes unused so remove it. Also remove
associated tests.
To continue to manage/unmanage services while CTDB is running:
* Start service by hand and then flag it as managed
* Mark service as unmanaged and shut it down by hand
In some cases CTDB does something fancy - e.g. start Samba under
"nice", so care is needed. One technique is to disable the
eventscript, mark as managed, run the startup event by hand and then
re-enable the eventscript.

LVS now uses a configuration file specified by CTDB_LVS_NODES and
