Clarify remote dependencies and auto-apply "parsable" directive

[Andrew-S-Rosen]

This PR closes #48 and does two things:

1. Adds installation instructions related to dependencies on the remote machine.
2. Auto-applies the parsable option if not set since this is required by covalent to read the queue status and other slurm information.

• [x] I have added the tests to cover my changes.
• [x] I have updated the documentation, VERSION, and CHANGELOG accordingly.
• [x] I have read the CONTRIBUTING document.

Once approved, I will make the same change in the covalent docs for the SLURM executor.
