Subject: [PATCH] [gareth] Add support for creating the dev env

This commit adds the code which automates most of the
setup. It forks all the repos, clones them and sets the
upstream accordingly.

Usage:
```
$ gareth -t xxxx -s sources --create
```

+title: Add support for creating the dev environment
+category: added
+author: Venu Vardhan Reddy Tekula <venu@bitergia.com>
+issue: null
+notes: >
+    The support for creating the developer environment
+    is added. This feature would automate most of the 
+    process of the setup.
+    
+    It forks all the grimoirelab repositories using the
+    token and clones them to the local machine into a 
+    given source. Later, it sets the upstream to all the
+    repositories accordingly.
+
+    Usage:
+    ```
+    $ gareth -t xxxx -s sources --create
+    ```
