Clean up work_type processing and fix execution vs control capacity (#10930)

* Clean up added work_type processing for mesh_code branch

* track both execution and control capacity

* Remove unused execution_capacity property

* Count all forms of capacity to make test pass

* Force jobs to be on execution nodes, updates on control nodes

* Introduce capacity_type property to abstract some details out

* Update test to cover all job types at same time

* Register OpenShift nodes as control types

* Remove unqualified consumed_capacity from task manager and make unit tests work
