Fix make install

Running `make install` fails with error:

  The CustomResourceDefinition "openstackcontrolplanes.core.openstack.org" is invalid: metadata.annotations: Too long: must have at most 262144 bytes

This patch fixes this problem by using `kubectl replace` instead of
`kubectl apply`.

Replace was chosen over `kubectl apply --server-side` because the apply
may fail to merge with the existing CRD, whereas replace will not fail.
