adding in missing kinds to olm config (#72)

Signed-off-by: Adam D. Cornett <adc@redhat.com>

Issue #, if available:
N/A
Description of changes:
Adding in the missing `kinds` to the olm config file. This ensures that when the `bundle` is created via the release process that `operator-sdk` does not throw any `warnings`. This then allows the PR to the community repos to be raised without any issues since the community repos run `operator-sdk validate bundle` which may reject `warnings`.
