Compute totals with parallel groups and derivative coloring can hang depending on objective/constraint ordering

For the record, I'm able to reproduce this on my machine. with 2 procs OS==OSX python==3.9.15 openmdao=3.27.1-dev mpi4py==3.1.1 numpy=1.25.1 scipy==1.9.3 petsc4py==3.18.1 openmpi==4.1.4

Compute totals with parallel groups and derivative coloring can hang depending on objective/constraint ordering

If I add a second parallel constraint for the second component as shown below, the problem works fine and the hanging goes away: ``` prob.model.add_constraint('parallel_group.dummy_comp2.y2', lower=2.0, parallel_deriv_color='deriv_color2') ``` I think...

Moved pre/opt/post logic into the Relevance class.

I may have missed it in the PR @naylor-b , but was there a test added to catch the parallel derivative bug in the future?
