Several of the tests("It") in the e2e suite reuse the CRD.
However they each try to setup and tear down the CRD independently.
Since these tests can be running in parallel, causing intermittant
failures.
Added a new framework utility for creating CRDs per test.
Then making the relevant tests use the utility to prevent name
collision/race.
Fixed bazel build.
Factored in fixes for @caesarxuchao
Making suggested change for @janetkuo
