fix: add more dataproc error handling

[leahecole]

Description

Adds AlreadyExists to a few more dataproc use cases, and in the case of the "create_cluster" test, does a quick check to make sure that the existing cluster is recent - which would allow us to assume it was created as part of this test

Fixes #9513
Fixes #9445
