Fixes: #728

Description of the change:

• Removed minimal mode support in v1beta2 API.
  • I left the network resources (i.e. ingress, route) for grafana intact utill feat(deploy): deploy cryostat 3.0 #727 that deploy cryostat3 behind proxy.

Motivation for the change:

See #728

How to manually test:

Set up and rebuild images:

export IMAGE_NAMESPACE=quay.io/<namespace>
export IMAGE_VERSION=3.0.0-remove-minimal
make oci-build bundle bundle-build
podman push quay.io/<namespace>/cryostat-operator:$IMAGE_VERSION
podman push quay.io/<namespace>/cryostat-operator-bundle:$IMAGE_VERSION
make deploy_bundle

With OpenShift:

yq .spec.minimal=true config/samples/operator_v1beta1_cryostat.yaml | oc apply -f -

With k8s (and Nginx Ingress Controller):

Create a CR with the following specs in this https://gist.github.com/tthvo/4be15d6ad0b52c5e1d6ee6f053f12371.

kubectl apply -f <path-to-cr.yaml>

Watch the beta1 CR converted to beta2 without minimal mode and the k8s resources are created correctly as in non-minimal mode.
