Remove "hybrid" out of this operator's name

[rebbuh]

I suggest to remove the term "hybrid" out of this operator's name. In the cloud context, "hybrid" typically refers to a setup where some parts of the resources reside in a (public) cloud and other parts reside on on-premises solutions.

As far as I can see, this operator has nothing to do with this meaning of "hybrid", which is misleading. "Multi" is rather the term that seems to describe what this operator is for.

Therefore, I suggest to rename this operator, to e.g.
multi-cloud-amqp-operator
k8s-amqp-operator
amqp-operator
...
