Update role for new source build process

The variables cloudkitty_developer_mode and cloudkitty_venv_download
no longer carry any meaning. This review changes cloudkitty to
do the equivalent of what developer_mode was all the time,
meaning that it always builds the venv and never requires
the repo server, but it will use a repo server when available.

As part of this, we move the installation out of its own file
because it's now a single task to include the venv build role.
This is just to make it easier to follow the code.

We also change include_tasks to import_tasks and include_role
to import_role so that the tags in the python_venv_build role
will work.
