Make rabbitmq user and vhost name shorter in kuttl tests

Some recent change (maybe [1a)], the string used in infra-operator for
rabbitmquser creation has changed from
`nova-kuttl-notification-transport-nova-notifications-user`
to `rabbitmq-notifications-nova-notifications-user-nova-notifications`
which is longer that 63 char openshift limit, leading to error:

RabbitMQ user error occurred Secret "rabbitmq-user-rabbitmq-notifications-nova-notifications-user-nova-notifications" is invalid: metadata.labels: Invalid value: "rabbitmq-notifications-nova-notifications-user-nova-notifications": must be no more than 63 characters

While this may be understood as a bug, this patch is making vhost and user names
shorter to unblock the kuttl test.
