[SYNPY-1653] Adding tests and re-attach session logic

[BryanFauble]

Problem:

• When creating a new grid session we have an opportunity to attach back to an active session when the user is using a record_set_id
• Integration tests were needed in order to test out the logic, which is now available in the dev environment
• Could not delete a grid session

Solution:

• Allow attaching back to active grid session when creating one for an existing record_set_id
• Allowing deleting grid sessions
• Adding in tests

Testing:

• Integration tests to cover logic

Any reason this is here and not in the Protocols folder?

I've started to prefer that they end up being in the same python script so they're "next" to eachother and easier to see what's really going on, but both are valid.

Hi @BryanFauble ! Thanks for your hard work. I tested out most of the examples, and they all worked great. I saw project_id="syn9876543" got included in multiple examples in the docstring, and I am thinking you might want to change it to a test project id?

I noticed you can start a grid session with grid.create(). But how do you edit the grid programmatically in Python? Or the grid will have to be edited in the UI? And is it possible to have multiple active grid sessions? If so, which session will you get when you run grid.create(attach_to_previous_session=True)?
