Brushy Brushy

Things in this release:

• Pinned the grype version, which will help security teams attest that "this tag of the admisson controller deploys this version of grype" which is v0.33.0
• Updated the README
• No version specified in gen_certs.sh now pulls the latest tagged version.
• Added help to gen_certs.sh to catch people looking for help.

Initial release

We think grype is pretty cool, so we wrote an admission controller to use grype to help us keep our clusters secure! This is the initial public release of that project.
