also verify that we actually do have a natgw master available if this is configured and make the node unhealthy if not.
(This used to be ctdb commit 7f273ee769d671d8c8be87c9187302fb77e814f3)
This node flag means the node is DISABLED and that all its public ip addresses
are failed over, but also that it has been removed from the VNNmap.
A STOPPED node should be in recovery mode active untill restarted using the continue command.
Adding two new commands "ctdb stop" "ctdb continue"

* 2 new tests for NFS failover.
* Factor repeated code from tests into new functions
select_test_node_and_ips(), gratarp_sniff_start() and
gratarp_sniff_wait_show(). Use these new functions in existing and
new tests.

cluster_is_healthy() is now run locally in tests and internally causes
_cluster_is_healthy() to be run on node 0. When it detects that the
cluster is unhealthy and $ctdb_test_restart_scheduled is not true,
debug information is printed. This replaces the previous use of
$CTDB_TEST_CLEANING_UP.
To avoid spurious debug on expected restarts, added scheduled
restarts to several tests.

This works around potential race conditions in the init script where
the restart operation is not necessarily reliable. It just wraps the
actual restart in a loop and tries for a successful restart up to 5
times.

3 separate tests:
* Check that gratuitous ARPs are received and take effect.
* Check that ping still works after failover.
* Check, via SSH, that the hostname changes after failover.

* Removed a race from tpcdump_start(). It seems impossible to tell
when tcpdump is actually ready to capture packets. So this function
now generates some dummy ping packets and waits until it sees them
in the output file.
* tcpdump_start() sets $tcpdump_filter. This is the default filter
for tcpdump_wait() and tcpdump_show(), but other filters may be
passed to those functions.
* New functions tcptickle_sniff_start() and
tcptickle_sniff_wait_show() handle capturing TCP tickle packets.
These are used by complex/31_nfs_tickle.sh and
complex/32_cifs_tickle.sh.

There are still very rare cases where IPs haven't been reallocated
before the beginning of the next test, so this adds a sleep and an
extra call to "ctdb recover" to restart_ctdb().

* ctdb_restart_when_done() now schedules a restart by setting an
explicit variable that is respected in ctdb_test_exit(), rather than
adding a restart to $ctdb_test_exit_hook. This means that restarts
are all done in one place.
* ctdb_test_exit() turns off "set -e" to make sure that all cleanup
happens.
* ctdb_test_exit() now prints a clear message indicating where the
test ends and the cleanup begins. This message also includes the
return code of the test.
* Add debug in cluster_is_healthy to try to capture information about
unexpected unhealthiness when a test starts.
* Simplify simple/07_ctdb_process_exists.sh so that the exit code is
generated more obviously.
* Remove redundant calls to ctdb_test_exit at the end of tests, since
they're done automatically via a trap. Also remove any preceding
warnings of restarts or final hints about test success/failure.
* Allow multi-digit debug levels in simple/12_ctdb_getdebug.sh and
simple/13_ctdb_setdebug.sh.

* Move building of CTDB_OPTIONS to new function build_ctdb_options()
and have it use a helper function for readability.
* New functions check_persistent_databases() and set_ctdb_variables().
* Remove valgrind-specific stop code, since the general pkill should
kill ctdbd when running under valgrind.
* Remove some bash-isms (e.g. >& /dev/null) since the script is /bin/sh.
* Make indentation consistent.
* Minor clean-ups.

This will force a wait until the ip addresses have been reallocated after a disable/enable command and will make scripting of enable/disable more predictable.
This will cause the command enable/disable to wait until the ip realocation that normally follows shortly after a enable/disable to finish before the command returns to the prompt.
