pgoapi.exceptions.UnexpectedResponseException: Unexpected HTTP server response - needs 200 got 502

Steps to Reproduce

Nothing in particular -- just started happening as of 23:25 UTC, is now happening frequently.

502 is bad gateway, so the servers may be overloaded; we should catch this exception and retry.

Niantic is starting to change things ... getting this too, and some other like 'GET_INVENTORY']['inventory_delta']['inventory_items'] KeyError: 'inventory_delta'

[JSchwerberg]

Well, 502 is just an HTTP error code for Bad Gateway; I'm willing to put money on their infrastructure just being overloaded.
Either way, #2407 was submitted to catch this one and retry, using similar logic to your fixes for throttling in the refactor :)
