Implement testing with Ceph

- Adds a few extra missing dependencies to install-deps that were
  not present in a fresh ubuntu vm.
- Adds a script to install Ceph, copied over from a different
  action that we're already using to test a different repo.
- Adds testing to the test-build action and renames it to test.
- Disable memory leak testing for test-seq and makes it the only
  test run.
