This is part of **"Why my PR is not merged?"** patch set series.
Since #50107 there one more tunable that can increase the cleanup period
- max_cleanup_delay_period.
Plus, increase the delay for the cleanup thread, otherwise it is too
fragile.

This PR formats all the `*.py` files found under the `tests/integration`
folder. It also reorders the imports and cleans up a bunch of unused
imports.
The formatting also takes care of other things like wrapping lines and
fixing spaces and indents such that the tests look more readable.
