Log message:
py-cachelib: updated to 0.3.0

Version 0.3.0
-------------
-   Optimize ``FileSystemCache`` pruning.
-   Fix a bug in ``FileSystemCache`` where entries would not be removed
    when the total was over the threshold, and the entry count would be
    lost.
-   ``FileSystemCache`` logs system-related exceptions.
-   Removal of expired entries in ``FileSystemCache`` is only triggered
    if the number of entries is over the ``threshhold`` when calling
    ``set``. ``get`` ``has`` still return ``None`` and ``False``
    respectively for expired entries, but will not remove the files. All
    removals happen at pruning time or explicitly with ``clear`` and
    ``delete``.

Version 0.2.0

Support for Python 2 has been dropped. Only Python 3.6 and above are supported.
Fix FileSystemCache.set incorrectly considering value overrides on existing keys \ 
as new cache entries.
SimpleCache and FileSystemCache first remove expired entries, followed by older \ 
entries, when cleaning up.
Fix problem where file count was not being updated in FileSystemCache.get and \ 
FileSystemCache.has after removals.
When attempting to access non-existent entries with Memcached, these will now be \ 
initialized with a given value delta.
