MDL-70795 reportbuilder: custom report filters editor.

Implement module for filters editing, allowing the report
editor to define which filters are available when users
are viewing the report.

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.
