feature: Environment Rancher Catalog

# Proposal

Enable the microservices project to run under Rancher using a Catalog Repository.

It is a cool feature because it allows deploy to all the services under a cluster using Cattle, the default orchestrator of Rancher.

Also, it enables an easier way to deploy all services in one click, on any environment.

## Features

Here lays the features that would be nice for the Catalog to enable:

- Environment Catalog
- [ ] Be able to receive a list of git repository to use as the services.
- [ ] Be able to extend every git repository root `docker-compose.yml` service definition automatically, and its dependencies.
- [ ] Be able to receive the services definitions and its dependencies.
- [ ] Be able to use a git repository, clone it, and simply run its `docker-compose.yml` file

Start by reviewing the root docker-compose.yml files and the Rancher Catalog Repository requirements described in the proposal. Define how a catalog would receive service Git repositories or service definitions, resolve dependencies, and run the resulting compose configuration. Done means the listed catalog deployment scenarios are supported and documented.
