Background

Split from:

• Contention system test with different operations at once #2546

Description

We'd like to enable the table metrics generation lambda to run on its schedule as a system test runs. We'd like to add this to the JUnit-based contention test being built for #2546.

This should be able to be turned on at a certain point in the test, after some setup. It should be turned off automatically at the end.

Analysis

We'll need DSL changes to turn the rule on and off.

Note that this will work at an instance level so we'll want to only use it for an instance that is specific to a single test. We could configure for each system test instance whether it's for a single instance or multiple, and validate this when we do anything within a test that operates at the instance level.
