Add a module for the Ganeti lock structure

Already provide a module holding the structure of the locks
available in Ganeti, so that the overall structure of WConfD
can be implemented. The actual locks still have to be added.

Verify atomicity of lock updates

Add a test verifying the atomicity of an update, i.e., if an update
succeeds, then all requests must be satisfied in the final state, and
if it fails, the state must be unchanged.
