Add Ready column to KafkaAccess and add KafkaAccess to strimzi category

[MichaelMorrisEst]

This PR adds a "Ready" column as an additional printer column on the KafkaAccess CRD, for example:

$ kubectl get kafkaaccess -n myproject
NAME              LISTENER   CLUSTER      USER      READY
my-kafka-access   tls        my-cluster   my-user   False

and also adds KafkaAccess to the "strimzi" category

$ kubectl get strimzi -n myproject
NAME                                            LISTENER   CLUSTER      USER      READY
kafkaaccess.access.strimzi.io/my-kafka-access   tls        my-cluster   my-user   False

NAME                                                  PODS   READY PODS   CURRENT PODS   AGE

strimzipodset.core.strimzi.io/my-cluster-controller   3      3            3              7h10m
