Log message:
py-flask-caching: updated to 1.7.0

Version 1.7.0:
**This is the last version supporting Python 2!**
- Added a feature called 'response_filter' which enables one to only
  cache views depending on the response code.
- A DeprecationWarning got turned into a TypeError.

Version 1.6.0:
- The delete_many function is now able to ignore any errors and continue
  deleting the cache. However, in order to preserve backwards compatibility,
  the default mode is to abort the deletion process. In order to use the new
  deletion mode, one has to flip the config setting CACHE_IGNORE_ERRORS to
  True. This was and still is only relevant for the **filesystem** and
  **simple** cache backends.
- Re-added the gaememcached CACHE_TYPE for improved backwards compatibility.
- Documentation improvements
