RabbitMQ integration

[javierdelapuente]

Applicable spec: ISD175 - RabbitMQ support in paas-charm

Overview

Support RabbitMQ in paas-app-charmer.

There are two different charms that provider RabbitMQ, rabbitmq-server and rabbitmq-k8s. A new library has done, based on the one in rabbitmq-k8s, paas_app_charmer.rabbitmq.RabbitMQRequires that provides a common interface to both charms, and provides a RabbitMQParameters model with the rabbitmq information. This is the same as the one in the charm state, as that library is just use in this project.

Documentation will be done outside of this PR.

fetch-lib has been changed everywhere to fecth-libs as charmcraft stable already offers fecth-libs.

There are a bunch of messages that certain CVEs can be removed now, should we do that?
