moves pnnl_cleanup to .pre stage and removes files based on age

[jdmacam]

Updates the pnnl_cleanup job in .gitlab-ci.yml to:

• run during the .pre stage
• remove files based on age (over 6 hours old) to cleanup ci account space

https://stackoverflow.com/questions/56324070/with-gitlab-ci-how-to-disable-repository-clone-for-one-job - let's remove the cloning step for this pipeline.

[cameronrutherford]

Since this is touching GitLab CI, could we also do some configuration of the git strategy for other pipelines?

I think we can disable cloning in the following:

• test_on_lassen
• test_on_quartz
• test_on_compute_node
• pnnl_cleanup

@nychiang for some reason the LLNL pipelines are also failing. I'm not as familiar with your CI setup (and don't have access), so feel free to clarify anything.

I don't know if this should just be addressed in a different PR, but it would also be good to re-factor to move away from YAML anchors, we well as separating each platform's CI pipelines into separate files for readability.

@jdmacam if you want to leave that for another PR, please create an issue to track the refactoring (along with viewing Ascent/Crusher pipeline status) and we can merge this sooner rather than later.

@cameronrutherford I resubmit the pipeline and everything looks good to me. Probably our platform was too busy when you launched the pipeline.

@cameronrutherford I've added the variable to those pipelines

LGTM and all pipelines pass. I think this can be merged.

You should notice tests passing a little bit faster as we will no longer have to clone the git repo before running tests where unecessary.
