Nearly all of these are simple textual substitutions, which preserve
the case of the original. A couple of minor cleanups were made in the
documentation (such as "LVSMASTER" -> "LVS leader").

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.
