This drastically simplifies the code. "ctdb reloadips" behaves the
same, since it causes a takeover run immediately after IPs are
deleted. "ctdb delip" now needs to be followed with an explicit "ctdb
ipreallocate".

RELEASE_IP sometimes times out because killing TCP connections can
take a long time.
The aim of the takeover timeout is actually to limit the total amount
of time for an IP takeover run. So, calculate a combined timeout
offset once and use it for each of the RELEASE_IP, TAKEOVER_IP,
IPREALLOCATED stages. This gives RELEASE_IP more time to kill TCP
connections but still limits the total time.

No preamble, just print keyword ENABLED or DISABLED. Fix the
documentation to reflect this and remove the text that is simply
wrong.
Also remove output from "ctdb enablemonitor" and "ctdb disablemonitor"
on success. This is just noise.

This makes the ctdbd setup explicit and allows multiple calls to

While here drop any unneeded ctdbd initialisation, such as VNNMAP and
IFACES. These have often been needlessly present, cluttering the
tests.

This limitation can be removed with a reasonable amount of effort. It
probably isn't worth doing until the public IP address configuration
is stored in a cluster-wide database. That seems like the right time
to change the API to handle the details that
CTDB_CONTROL_GET_PUBLIC_IPS doesn't currently retrieve.
