(PLATFORM-1077) Adding CI/CD capabilities and Unit Tests

[kbooker79]

This PR enables running of the standalone Stochastic Physics unit tests, and automation of the standalone unit tests through the addition of a jenkins pipeline integration. The pipeline is spun-up via git labels and executed through a newly created jenkinsfile script.

Hi, @kbooker79 . Can you please sync up the PR branch with master?

@JeffBeck-NOAA I tested out the unit test pipeline, following our changes. Following the srun command (srun --label -A epic -n 24 standalone_stochy.x), the pipeline failed with the below.

At line 182 of file compns_stochy.F90 (unit = 21, file = 'input.nml')
1: Fortran runtime error: Cannot match namelist object name do_spp:

Does do_spp need to be enabled in compns_stochy.F90 as well, perhaps?

[JeffBeck-NOAA]

Sorry, @zach1221. The following needs to be in the &gfs_physics_nml (not &nam_sppperts) section of input.nml:

do_spp = .true.
n_var_spp = 6 (if running with GF perturbations, 5 otherwise)

@JeffBeck-NOAA @jkbk2004 fyi, the unit tests with spp enabled are working now, following input.nml changes from Jong. I have also successfully tested the stoch physics unit test pipeline, with the new jenkinsfile. Please feel free to review.
