Simplify rt.conf

[climbfuji]

Description

Right now we have a lot of special treatments in rt.conf to run certain tests on some systems but not on others. For many of these tests, the exceptions were introduced in the past when something didn't run on certain systems (because it was currently developed, was missing input data, or the system had problems).

We need to check if these exceptions are still required or if we can remove some of them to cleanup rt.conf and facilitate the overall regression test cleanup that we are planning to do in the near future.

Solution

On a case-by-case basis, remove exceptions to run certain tests only on some platforms or to exclude certain platforms. Create new baselines and verify against them to make sure that the tests not only complete but also reproduce.

Alternatives

Deal with these exceptions later when doing the general overhaul of the global model regression tests.
