Add cache limits

[baumgold]

Is your feature request related to a problem? Please describe. Currently the size of the cache directory can grow unbounded. This can cause problems (e.g. disk full) and require manual intervention (e.g. manually deleting the entire cache directory).

Describe the solution you'd like Add size/age limits to the cache directory and the ability for users to enforce those limits by deleting the least recently used data with a function call. Similar to the "reduce_size" function in joblib.memory (link).

Describe alternatives you've considered A cron job to automatically remove the entire cache direction is a hack and seems like overkill.
