existing_stats - find fully qualified matches for the requested stats bucket

@param stats_type array of all statistics of this type (eg~ timers) to match
@param bucket string to search on, which can be fully qualified,
or end in a .* to search for a folder, like stats.temp.*

@return array of fully qualified stats that match the specified bucket. if
no matches, an empty array is a valid response
