nasbt does not exist in dev, nor was it introduced in this PR.

I think #2926 should cover it. I'll try rebasing that one on the latest dev.

- Resolves geopm#2681 - Introduces an agent that adjusts for imbalance by assigning more CPU frequency resources cores that spend less MPI time per epoch. - Agent supports control by P-States and/or SST core priorities.
- Resolves geopm#2682 - Add NAS-BT and AIB experiments - Add a plot generator
- Resolves 2682 - Introduces an integration test that checks for energy savings when the frequency_balancer is used with P-State control in an imbalanced application. If SST is present on the test system, the test also checks for performance improvement.

This set of changes introduces the frequency_balancer agent, which adjusts for imbalance by assigning more CPU
frequency resources cores that spend less MPI time per epoch. The changes include integration tests that check for energy savings, and also for performance improvement if SST is available on the test system.
