test: Add retries to increase reliability of test (#1319)

* Skip a flakey test

This test needs to be skipped as it is causing P1 issues to appear. We need a formal plan for reproducing this issue.

* Remove block of code for skipped test

This block of code is an after hook that will not work anymore now that the test is skipped because the test creates an instance and the after hook tries to delete it

* Add retry options

Add retry options to create table to ensure that there is enough time for the instance to get created in order to avoid flakey tests
