K8S dex-overlord.yaml ordering fix

Use Client defined in dex instead of go-oidc for storing clients

* TestCreateClient was missing test coverage on error cases
* Fixed bug where 500s were being reported for bad requests
* changed function signature of NewAdminAPI back to old way of passing
  in lots of repos: passing in a DbMap made it difficult to test
* added swappable ID and Secret generators when creating Clients

It's never used by downstream code, and besides, it's not really the
secret but a Hash of the secret.

Also require client ID and secret.

Get rid of all outdated "ClientIdentity" terminology.

This is instead of oidc.ClientIdentity. This makes it easier to add new
fields custom to dex to the client.

Update examples/README.md
