Flushing the events cache worked by updating a recent number of rows in
the "events" table. This has the result that on PostgreSQL a lot of dead
tuples are produced on a regular basis. This in turn means that
PostgreSQL will spend considerable amounts of time vacuuming this table.
This in turn can lead to an increase of database load.
For GitLab.com we measured the impact of not using events caching and
found no measurable increase in response timings. Meanwhile not flushing
the events cache lead to the "events" table having no more dead tuples
as now rows are only inserted into this table.
As a result of this we are hereby removing events caching as it does not
appear to help and only increases database load.

added spec for avatar saver
avatar saver!
added avatar restorer spec
fix spec
added avatar restorer class
fix export service
fix warnings, added changelog
fix spec
some refactoring based on feedback
fixed a few issues after testing i/e avatar
- Avoid multiple calls to `validates` for the avatar attributes.
- In a cropping process, don't check if the model inherits `User`, check if it responds to `:avatar_crop_size`.
This commit moves the note folder from
/public/uploads/note
to
/uploads/note
and changes the uploader accordingly.
Now it's no longer possible to avoid the access control by modifing the url.
The Avatar upload has been refactored to use an own uploader as well
to cleanly seperate the two upload types.
