The "natgwlist" command is no longer marked "auto all" and is also
marked "without daemon". That latter is not strictly true because
ctdb_natgw needs the daemon so a subsequent invocation of "ctdb
nodestatus" will work. However, "without daemon" is used here because
the top-level "ctdb natgwlist" does not need to open a connection to
the daemon. It just needs to invoke ctdb_natgw.
Update tests to suit.
It would make sense to make "ctdb natgw" generally call out to
ctdb_natgw, passing all argument. However, that can be done later.

"ctdb reloadnodes" currently does no sanity checking of the nodes
file. This can cause chaos if a line is deleted from the nodes file
rather than commented out. It also repeatedly produces a spurious
warning for each deleted node, even if the node was deleted a long
time ago.
Instead compare the nodemap with the contents of the local nodes file
to sanity check before attempting any reloads. Note that this is
still imperfect if the nodes files are inconsistent across nodes but
it is better. Also ensure that any nodes that are to be deleted are
already disconnected. Avoid trying to talk to deleted nodes.
The current implementation is a bit unfortunate when it comes to
deleting nodes. The most obvious alternative to the above complexity
would be to reloadnodes on the specified node first, then fetch the
node map (in which newly deleted nodes would be marked as such) and
then handle the remote nodes. However, the implementation of
reloadnodes is asynchronous and it only actions the reload after 1
second. This is presumably to avoid the recovery master noticing the
inconsistency between nodemaps and triggering a recovery before all
nodes have had their nodemaps updated.
Note that this recovery can still occur if the check is done at an
inconvenient time. A better long term approach might be to quiesce
the recovery master checks while reloadnodes is in progress.
Update a unit test to reflect the change.

Recent changes have caused these commands to attempt to get
capabilities from all nodes before doing further filtering. This
means that capabilities are unnecessarily fetched from nodes that are
unlikely to be the master. If such a node does not answer the control
then many nodes can fail to calculate the master node. In the case of
natgwlist this will cause "monitor" events to fail resulting in
unhealthy nodes.
Restore the behaviour where capabilities are only fetched for a node
that will be the master if it has the desired flags.
Although this masks a problem where a connected node is not replying,
it can help to avoid an outage in some cases.
Add supporting tests and infrastructure. Infrastructure just lets a
timeout be faked - just for ctdb_ctrl_getcapabilities_stub() so far.
First test checks that this infrastructure works if the first node
times out in natgwlist. Second test checks the case worked around by
the above fix - that is, no failure when a node with PNN beyond the
NATGW master can time out.

Commit ba69742ccd missed the point of
filtering disconnected nodes while limiting the nodemap to those in
the NAT gateway group. It was really to avoid trying to fetch
capabilities from disconnected nodes. This should be explicitly done
in filter_nodemap_by_capabilities(), otherwise "ctdb natgwlist" simply
fails when there is a disconnected node.
Note that the alternate solution where filter_nodemap_by_flags() is
called before filter_nodemap_by_capabilities() would not be not
correct. Filtering on flags first can produce a "healthier" set of
nodes where none of them have the NAT gateway capability.
Also extend stub for ctdb_ctrl_getcapabilities() to fail when trying
to get capabilities from a disconnected node and add a corresponding
test to confirm that "ctdb natgwlist" is no longer broken.

This needs a proper fix to distinguish between timeout and failure
conditions and take appropriate action.

(e.g. memory allocation failure) and an unknown tunable.
