Commit 96276ae7 added the above opcode, but forgot to update the OP_ID
per our previous mailing list discussions. This patch makes the OP_ID
be consistent with the other IDs (OP_$object_$action).

Currently, the unittest TestDispatchTable in mcpu unittest does a
hard-coded approach to test whether an opcode should be included or
not in the mcpu.Processor dispatch table. This is not flexible, so we
replace it with two changes:

- first, we do not return the base OpCode in opcodes.OP_MAPPING;
  rationale being that we shouldn't need to serialise or deserialise
  this opcode during normal operation
- second, we add a new attribute WITH_LU (other name suggestions
  welcome) to the base opcode set to True, and we explicitly set it to
  False in OpTestDummy, thus automatic skipping of such LUs in the
  unittest (and in other places)

To correct for the new behaviour, the tests in the opcode unittests
are updated to include OpCode explicitly.

Note: we also replace assert_ with assertTrue in the affected unittest
(as assert_ is deprecated in 2.7).

The source cluster has to shut down an instance before it can be

When moving the opcode parameters I moved two or three checks from an

In the context of a node, its group has (at least today) only one
meaning, that is the node's node group. As such, we rename
node.nodegroup to just node.group.

Note: if we want to keep node in there, it should be at least
node_group, for consistency with the other node attributes.

Similarly, we rename the OpAddNode nodegroup attribute to group.

In order to support priorities, the processing of jobs needs to be
changed. Instead of processing jobs as a whole, the code is changed to
process one opcode at a time and then return to the queue. See the
Ganeti 2.3 design document for details.

This patch does not yet use priorities for acquiring locks.

The enclosed unittests increase the test coverage of jqueue.py from
about 34% to 58%. Please note that they also test some parts not added
by this patch, but testing them became only possible with some
infrastructure added by this patch. For the first time, many
implications and assumptions for the job queue are codified in these
unittests.
