ctdb-tools-ctdb: Make natgwlist and lvsmaster more resilient 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.
