Create 5 Tests to support VSphere in component readiness

Doe when:
1) All tests shows 7 days of passing
2) All the bugs that surface from this testing are resolved

Status:
Manually verified that the new tests for vSphere are passing.

Currently it needs the following PRs to execute correctly:

1) MCO-1657: FeatureGate for Bootimage updates for the vSphere platform api#2301
Needed for the ManagedBootImagesvSphere FeatureGate
2) MCO-1307: Add support for VSphere for BootImage Update machine-config-operator#4677
ValidationAdmissionPolicy managed-bootimages-platform-check to allow VSphere as the BootImageUpdatePlatform.
To do:

Add another E2E Test
Steps:
Scales down a MachineSet replicas -= 1
Waits for a successful bootimage update
Scales up the MachineSet replicas += 1
Verifies the new Machine spawned should have been booted from the updated bootimage (possibly by looking at the MCD log aleph version)
