Adds clusters for the in place upgrades tests

[igooch]

What type of PR is this?

/kind feature

What this PR does / Why we need it:

Adds GKE Autopilot and GKE Standard test cluster for use in the In Place Upgrades tests. The clusters follow the same pattern as the existing e2e test clusters. The Upgrades standard cluster do not require as much compute as the e2e clusters, so the initial node count is lower than for the e2e tests.

Which issue(s) this PR fixes:

Working on #3795

Approved. We can do some refactoring to reduce the redundant code used for both e2e and upgrade as a follow up.
