Add SGE Testing Container

[chasejohnson3]

The SGE tests in test_submitter.py only run if the current environment has SGE available (similar to SLURM). Add a container for testing the SGE framework, so these tests can run and further testing can cover the SGEWorker.

Tests to be added for SGEWorker include:

• Test evicted jobs are resubmitted
• Test multiple tasks are collected and submitted into a single SGE job array

Since SGE is becoming less common, we should probably move it into a plugin until it can be tested properly

Maybe we should do this for SLURM as well and just keep the debug and CF workers in the main repo. It means we wouldn't rerun the SLURM tests for every change, which I think probably isn't necessary
