deprecation warnings when deploying the operator

[mythi]

kubernetes 1.19 gives the following warnings. When the right time comes, let's move away from v1beta1.

TODO:

• move the FPGA CRDs to v1 API
• move to v1 RBAC API
• test by deploying a device CR with the operator
• test using make test-with-kind
