As pointed by cz8s in https://github.com/leapcode/leap_mx/pull/75, this
path was fixed in the debian branch for platform 0.7, but was never
merged back onto develop.

Some refactor on the couchdb usage was needed to be able to mock
couchdb.

- Resolves: #7435

this is part of a process to make the setup of the development mode less
troublesome. from now on, setting up a virtualenv in pure development
mode will be as easy as telling pip to just install the external
dependencies::

  pip install -r pkg/requirements.pip

and traversing all the leap repos for the needed leap dependencies doing::

  python setup.py develop

There are some reasons to remove the initscript from the python package:

  1. To include the initscript it in the python package it is necessary to
     assume a lot of things about the system in which the package would be
     installed.

  2. The debian packaging system will correctly create an initscript by
     itself.

  3. We don't have to maintain 2 different setup.py files (one in
     master/develop branch and another in debian package branches).
