Add get_pods() API method

[alexeevit]

Hey, I just needed a method to get all my pods and didn't find it in the repo.
Here's my humble implementation.

BTW, I tried to add get_pod(pod_id : str) method, but when I added (input: {id: "{pod_id}"}) to the query, I got GraphQL validation error. I'm not really familiar with GraphQL so would be happy if you directed me.

Thank you for the PR! If you get a moment may you please refactor/reformat to pass the lint check: test_ctl_commands.py:145:0: C0301: Line too long (133/100) (line-too-long)

Easy, done.

Do you have any ideas how to build a query to get only one pod by id? I think we should add it for consistency.

Assuming you already looked over this? https://graphql-spec.runpod.io/

Also super clean PR, thank you for putting in the time to make it so comprehensive and include tests :)
