Fix common-instancetypes func tests with HCO

What this PR does / why we need it:

The functional tests currently assume that SSP is deployed standalone without HCO. However these same tests are also used downstream in a slightly different context where we initially deploy the environment using HCO. As such the common-instancetypes tests are invalid and need to be skipped. This series adds some limited coverage for this scenario ensuring that SSP ignores the virt-operator deployed resources.

More comprehensive coverage needs to be added to HCO to assert the default behaviour of virt-operator and ssp-operator in environments where HCO is still actively reconciling both.
