Rewrite of TPS integrations using basic bash scripts

[mars]

Through work & pairing with @halorgium, we've got a more testable approach for CLI's TPS integrations.

The scripts release/tps_check_lock& postrelease/tps_record_release are now similar bash scripts, making these much easier to reason about.

They each:

1. parse env vars & arguments, returning clear error messages for missing inputs
2. implemented as a single curl command capturing response status code and response body
3. retry using a basic loop, with sensible timeouts for each
   1. 10-minutes for checking the lock
   2. 30-minutes for recording the release
4. logs clear error message (response status & body) during retries
