Initialize operator project

Command executed: `operator-sdk init --domain onepassword.com --repo github.com/1Password/onepassword-operator --plugins=go/v4-alpha --license=none`
- `--plugin=go/v4-alpha` is used to enable support for Apple Sillicon environments.
- `--license=none` is used since the only option is Apache, and we use the MIT license. `hack/boilerplate.go.txt` is updated with the MIT license instead.

+# leaderElectionReleaseOnCancel defines if the leader should step down volume

+# In the default scaffold provided, the program ends immediately after
