Api-Break
- Upgrade configuration hierarchy, add multi-db support, and change dump key format [Wes Kendall, 5edeeb8]
``django-pgclone`` has ``settings.PGCLONE_CONFIGS`` to support re-usable command
options. Dump keys were changed to capture the config and also contain a configurable
database instance to better distinguish different databases.
Multi-database setups are fully supported.
Docs were revamped and overview all settings and configuration possibilities.
Instructions for migrating to version 2 are in the "Frequently Asked Questions" section of
the docs.
