 morss uses caching to make loading faster. There are 3 possible cache backends:
 
 - `(nothing/default)`: a simple python in-memory dict-like object.
-- `CACHE=sqlite`: sqlite3 cache. Default file location is in-memory (i.e. it

-- `CACHE=mysql`: MySQL cache. Connection can be defined with the following
