What this PR does / Why we need it:
We have adopted remote backend (GCS) for the e2e test cluster terraform state, but the target for creating e2e test clusters doesn't verify whether the state bucket exists, which introduces confusion. This PR adds dependencies to the creating e2e test clusters target to verify and create the state bucket if it isn't created yet.
