Clean up remove_locks

Locks are now identified by their name, and no longer
a resource in the master daemon. In particular, there is
no more need for explicitly removing the locks; freeing
them is enough.

Get instance secondary nodes from config

Use 'GetInstanceSecondaryNodes' to get the secondary nodes of an
instance, instead of the 'secondary_nodes'.
Annotate 'secondary_nodes' in rpc so that backend has access to it.

Make configuration per job/thread

Previously there was one shared configuration object for all jobs,
threads and other tasks. This patch creates separate ConfigWrite
instances for distinct jobs/threads.

All exported methods of ConfigWriter are now wrapped in calls that...

Add a thread ID to the WConfd client id

This allows to distinguish threads that don't have a job id, which is
needed for answering queries.

Since Python thread IDs aren't guaranteed to be unique, in future it'd
be preferable to use a different, unique identifier....

Make mcpu acquire WConfD locks

So far, the mcpu acquires locks that live in memory
of masterd. This design does not fit with our jobs-as-processes
goal. So make mcpu acquire the corresponding locks in WConfD
instead.

Note that this implies changes in various other files that call...

Use node UUIDs for executing LU hooks

LUNodeAdd, the only LU using a node name still, is changed to overwrite
PreparePostHookNodes() and use node UUIDs only as well.
This allows to remove the support for 3-tuples as results of
BuildHooksNodes() and removes the translation to node names....

Add PreparePostHookNodes to LUs

This method can be used to alter the list of node UUIDs on which post
hooks are executed. PreparePostHookNodes is called after Exec, so LUs
can use data only known after the execution of the LU.
