Subject: [PATCH 02/13] traversers: support MATCH_GROW_ALLOCATION match op

Problem: adding support for growing an allocation requires a new
match_op.

Add match_op_t::MATCH_GROW_ALLOCATION to the traverser. While the new
match operation behaves identically to MATCH_ALLOCATE in the traverser,
creating a new operation is clearer in intent.

Subject: [PATCH 08/13] rq2: add support for grow_allocation

Problem: adding support for growing an allocation requires handing the
grow_allocation command in rq2.

Add the grow_allocation command to rq2 and add error handling for
nonexistent jobids.
