metrics: Add memory footprint tests to the CI

This PR adds memory foot print metrics to tests/metrics/density
folder.

Intentionally, each test exits w/ zero in all test cases to ensure
that tests would be green when added, and will be enabled in a
subsequent PR.

A workflow matrix was added to define hypervisor variation on
each job, in order to run them sequentially.

The launch-times test was updated to make use of the matrix
environment variables.

Fixes: #7066
