Add install -e option

[chouseknecht]

Similar to pip install -e. The -e option will enable Ansible to find and execute content found in a local project directory structure.

As a developer I want to create a new collection, so I run mazer init foo, to create a new Ansible Collection named foo in the current working directory. This new project is not in the Ansible content path, so Ansible cannot see any of the content I add to the collection.

To make the content visible to Ansible, I will run mazer install -e foo, and Mazer will add the appropriate symlinks, and thus make any new content added to the project accessible to Ansible.

The command should support:

• . for the current working directory
• A path to a project
• A -g or --global option to add the project to the global content path
