Extend usage of pin cores feature for all targets running tests

Extending feature usage with newest and recently added CI platforms
  - openSUSE 15.6
  - SLES 15 SP6

The feature enables 1:1 pinning of CPU cores for VM, which should mean
more stable CPU allocation from host and fewer sporadic failure.

The down side of this is that the targets will effectively use double
the capacity from the host that they previously would. It is to be seen
how effective this is in reducing flakiness, which would counter the
increased usage by reducing staging needed.

In Coin the feature is limited so that it only affects test VMs.
