This function for create django site project work flow on remote server.
Django site source cloning from remote git repository.

For this need setup global `env` dict.

env.user - deploy user name (use for ssh)
env.password - deploy user password (use for ssh)
env.hosts - list deploy hosts (use for ssh)
env.domain - django site domain (DNS) use for:
- nginx settings
- uWSGI start user
- project dir name
env.repository - remote git repository url, use for git clone site source

Abort if env.domain (env.repository) value not set or invalid.
