Use the VNN map from the node running node_has_status().
This means that
wait_until_node_has_status 1 notlmaster 10 0
will run "ctdb status" on node 0 and check (for up to 10 seconds) if
node 1 is in the VNN map.
If the LMASTER capability has been dropped on node 1 then the above
will wait for the VNN map to be updated on node 0. This will happen
as part of the recovery that is triggered by the change of LMASTER
capability. The next command will then only be able to attach to
$TESTDB after the recovery is complete thus guaranteeing a sane state
for the test to continue.
This stops simple/79_volatile_db_traverse.sh from going into recovery
during the traverse or at some other inconvenient time.

If the lock file is inaccessible or the inode number changes then the
lock is lost, so exit. This allows the recovery daemon to trigger an
election. The ensuing recovery will re-take the lock.
By default the lock file is checked every 60 seconds. A lot can
happen in 60 seconds but being more aggressive and accessing the lock
too often could result in a performance issue for the cluster
filesystem.
An new optional 2nd argument is added, which is the lock file re-check
time in seconds.

There is a chance that restoring IP addresses to the test node will
result in different IP addresses being assigned to that node.
Removing a single IP address may then fail (or be a no-op) if it is
done after the restore.
So, swap the single IP address removal to happen first, then restore,
then remove all IP addresses.
