fencing: Introduce getHostLeaseStatus API
When fencing another host, we like to check if the other host has access
to storage, to prevent unwanted fencing of a lively host. This patch
adds an internal API for getting another host status on monitored
domains.
The new getHostLeaseStatus API returns a dictionary of monitored domains
UUIDs and host lease status for each domain, as reported by the cluster
lock. The caller will apply a fencing policy using this data to decide
if host is lively enough to prevent fencing.
Here is an example result:
{'04e604d3-71eb-41e0-a8a3-74404bdd9d75': 'live',
'09049dc6-2007-492e-afd9-3ec201775b2a': 'dead',
'20501ea5-cf6b-453a-b23d-a708c28cec1f': 'live',
'2b02c759-2e4a-4cf0-9b8e-37a6ec77f821': 'unavailable',
...
'fc348be8-18f4-42ff-8421-9043203e13a6': 'live'}
See clusterlock.py for the possible statuses and their meaning.
