minimum engine version check protection for UCP enabled cluster #22

Open ruizmarlon opened 4 years ago

ruizmarlon commented 4 years ago

Recommend adding a minimum engine version check logic based on the requirements of UCP.

In this example a cluster was created with `UCP 3.3.0' & '19.03.8'

Used cluster.yaml to downgrade '19.03.5'. This was allowed by launchpad.

The issue here is that the minimum requirement is '19.03.8'
