Updates for codegen, go 1.17, etc.

kubernetes/kubernetes#106964 fixed a bug whereby codegen outside of
GOPATH would put generated files under github.com/ relative to the repo
root. Revendor k8s.io/code-generator to pull in the fix and update our
script to use the --trim-path-prefix flag it introduced.

The update resulted in dependency hell, including needing to move to go
1.17.

Changes in actual hive code to accommodate updated dependencies include:
- Accommodate a new method on workqueue.Interface.
- Remove the `--v` flag from the hiveadmission executable --
logging-related CLI options were removed from the underlying command at
some point.
- Rewrite the logr wrapper we pass to controller-runtime to initialize
the managers for the operator and controllers
- Repoint where we get our fake clock from for testing expectations.
