Fuel Config Reap + Additional Refactoring for Autodeployment

1. Refactor the whole autodeployment code in such a way that
the preparation of Fuel VM + networking and the autodeployment itself
can be executed all at once

2. Functionality added that allows reaping of Fuel configuration from
an existing environment and create DHA and DEA configuration files from it

JIRA: [BGS-2] Create Fuel deployment script
