Since filtering by these values is very rare (they're mostly just
displayed as-is) we don't need to waste any index space by saving them
as tags. By storing them as values we also greatly reduce the number of
series in InfluxDB.

Add new feature to find file(recreate)

While useful for finding out what methods/views belong to a transaction
this might result in too much data being stored in InfluxDB.

This reverts commit 7549102b.

Apparently I was wrong about
ActiveSupport::Notifications::Event#duration returning the duration in

- feedback(http://feedback.gitlab.com/forums/176466-general/suggestions/4987909-add-file-finder-fuzzy-input-in-files-tab-to-ju )
- fuzzy filter(https://github.com/jeancroy/fuzzaldrin-plus)
- shortcuts(when "t" was hitted at tree view, go to 'file find' page and 'esc' is to go back)
- depends on gitlab_git 7.2.22
