Install provider via Crossplane as a package in local dev environment

[ccremer]

Summary

• This PR gets rid of the Helm chart and installs the provider as a Crossplane package instead
• Seeing how Crossplane packages work and their installation, a local registry is required to avoid having to push a temporary image to a public registry just for testing.

Building the package fails for me with a linting error:

gmake package-provider
kubectl crossplane: error: failed to build package: failed to lint package: not exactly one package meta type
gmake: *** [package/package.mk:20: package-provider] Error 1

EDIT: renaming crossplane.yaml.template to crossplane.yaml fixes the issue. I guess something is supposed to transform the template file?

Having the same issue as @Kidswiss:
kubectl crossplane: error: failed to build package: failed to lint package: not exactly one package meta type
