512fa29cce ctdb-scripts: Change CTDB_SERVICE_NMB default value to 'nmb'
Till now 50.samba script was based on RHEL versions <=6 where we didn't
have separate start up script for nmb and smbd used to start nmbd when
required. Now that nmbd has its own start up script named "nmb" it is
reasonable to have "nmb" as default value for CTDB_SERVICE_NMB inside
new 48.netbios ctdb script.

cope with newly added script.

693080abe4 ctdb-scripts: Strip square brackets when gathering connection info
ss added square brackets around IPv6 addresses in versions > 4.12.0
via commit aba9c23a6e1cb134840c998df14888dca469a485.  CentOS 7 added
this feature somewhere mid-release.  So, backward compatibility is
obviously needed.

As per the comment protocol/protocol_util.c should probably print and
parse such square brackets.  However, for backward compatibility the
brackets would have to be stripped in both places in
update_tickles()...  or added to the ss output when missing.  Best to
leave this until we have a connection tracking daemon.

c5803507df ctdb-config: depend on /etc/ctdb/nodes file
BUG: https://bugzilla.samba.org/show_bug.cgi?id=14017

CTDB should start as a disabled unit (systemd) in most of the
distributions and, when trying to enable it for the first time, user
should get an unconfigured, or similar, error.

Depending on /etc/ctdb/nodes file will give a clear direction to final
user on what is needed in order to get cluster up and running. It should
work like previous ENABLED=NO variables in SySV like initialization
scripts.

b80967f5dc ctdb-scripts: Drop script configuration variable CTDB_MONITOR_SWAP_USAGE
CTDB's system memory monitoring in 05.system.script monitors both main
memory and swap.  The swap monitoring was originally based on
the (possibly incorrect, see below) idea that swap space stacks on top
of main memory, so that when a system starts filling swap space then
this is supposed to be a good sign that the system is running out of
memory.  Additionally, performance on a Linux system tends to be
destroyed by the I/O associated with a lot of swapping to spinning
disks.

However, some platforms default to creating only 4GB of swap space
even when there is 128GB of main memory.  With such a small swap to
main memory ratio, memory pressure can force swap to be nearly full
even when a significant amount of main memory is still available and
the system is performing well.  This suggests that checking swap
utilisation might be less than useful in many circumstances.

So, remove the separate swap space checking and change the memory
check to cover the total of main memory and swap space.

Test function set_mem_usage() still takes an argument for each of main
memory and swap space utilisation.  For simplicity, the same number is
now passed twice to make the intended results comprehensible.  This
could be changed later.

A couple of tests are cleaned up to no longer use hard-coded
/proc/meminfo and ps output.

failure (i.e. multiple nodes able to take the lock) will be confusing.

Instead, change the example setting to one that will result in banned
nodes, encouraging users to consciously configure (or deconfigure) the
recovery lock.  Tweak the corresponding comment.
