ganeti.query_unittest.py: test lock fields too

query2: Add new field status “offline”
This allows “gnt-node list” to show the difference between modes markedoffline and nodes with e.g. RPC errors (“(nodata)”). node1 is themaster, node2's node daemon crashed and node3 is marked offline:
$ gnt-node list -o name,offline,dtotal,dfree...

In upgraded configurations, some items might miss the “ctime” and/or“mtime” values and need to be handled specially.
query: Add definition for instance queries
Add node query definition
This includes a bunch of helper functions which can be helpful for otherqueries, too. Unittests are included.
