There's an internal race condition where when an rpc hits the timeout
limit, it sometimes receives a DEADLINE_EXCEEDED, but sometimes receives
a CANCELLED error. This PR marks CANCELLED as retryable, so this
situation will always eventually reach a DEADLINE_EXCEEDED state.

This will fix the flake currently seen in the conformance tests

Thank you for opening a Pull Request! Before submitting your PR, there
are a few things you can do to make sure it goes smoothly:
- [x] Make sure to open an issue as a
[bug/issue](https://github.com/googleapis/python-bigtable/issues/new/choose)
before writing your code! That way we can discuss the change, evaluate
designs, and agree on the general idea
- [x] Ensure the tests and linter pass
- [x] Code coverage does not decrease (if any source code was changed)
- [x] Appropriate docs were updated (if necessary)

Fixes #1239

Previously, when a channel refresh occurs, the async client would use
`channel.close()` with a grace parameter to allow previous channels to
keep serving old requests for a time. We were seeing flakes in our
tests, showing that `channel.close()` isn't reliable, and can sometimes
cancel ongoing requests before the grace period ends

This PR fixes this by using a fixed sleep time before calling close in
the async client, like the sync client already does. This should remove
the potential for cancelled requests before the grace period ends, and
improve test flakiness

I also updated the system test to fully capture this problematic state,
instead of encountering it in a random race condition
