(SE) Ability to run Tier 2 tests locally

[ashiklom]

The ability to trigger tier 1 tests via command line (e.g., swell t1test ufo_testing) is really convenient. We should create a similar capability for tier 2 (possibly, with finer-grained control, because the tests are bigger and will take longer to run).

The current Tier 1 local tests are defined here: https://github.com/GEOS-ESM/swell/blob/develop/src/swell/test/suite_tests/suite_tests.py

A similar structure could probably be used for Tier 2 tests.

The shell version of the Tier 2 workflows are defined here:
