There is no need for with_jenkinshash and with_mutexes flags, since the

Currently, every lock helper will log a message if it cannot get a lock.
This can spam the logs and overwhelm syslog if there are hundreds of
lock helpers waiting for contended record.
Instead keep track of the record for which we have already logged once
with specific timeout interval. If we get timeout interval larger than
the previously logged interval, then log again once. This will reduce
the amount of logs for contended records to a single log entry per 10
seconds per record.

there is no need to keep the empty records in the database since they
will never be recovered record-by-record using RSN.

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.

The non-blocking logging variants can currently silently drop messages
when the socket queue fills.
In this case, count the number of dropped messages and attempt to log
a message about dropped log messages when the next message is logged.

The "Number of nodes:" header should only be displayed when "all" is
specified. This is how the command behaved in Samba <= 4.4.
Printing the number of nodes is not helpful and is rather confusing in
the default case where only the status of the current node is printed.
