For cache types which mean this information can be obtained without a
significant performance cost (i.e. just by calling strlen and not
having to serialize something that wasn't serialized already),
this change calculates the size of data read from or written to cache

output (when that is turned on).

This supports the following cache types:

* File store
* Redis (only if caching is enabled)

These filters allow those users viewing the report to further
limit the data being displayed (after conditions have been
applied), by selecting their own values for each filter.
