-------------
- Fix: set default env.infrastructure at the very first time
- Change: ``fabricio.run()`` use current host (instead of current infrastructure) to generate cache key
- Change: ``DjangoContainer`` doesn't call ``backup()`` before applying migrations now
- Change: ``PostgresqlContainer`` doesn't contain ``PostgresqlBackupMixin`` now
- Enhancement: use ``remote_tunnel`` only if registry hostname is IP or alias of the remote host itself (`66`_)
- Enhancement: image, options and other container attributes now can be passed to the ``Container`` upon initialization
