tests: remove sleep hack to expire sql_cache_short
A number of tests sleep for 1.5 or 2 seconds to let the beaker cache
'sql_cache_short' expire. This cache is for example used for IP permissions;
tests changing such permissions need to make sure they take effect before
proceeding, especially when exiting from the test.
A much faster method is to effectively invalidating the caches.
Because it is difficult and fragile to only invalidate the relevant cache --
difficult to know exactly which cache needs to be invalidated, fragile
because the string indicating the cache line is not very nice and might
change in the future (in the case of IP permissions for the default user,
the cache is referred to with something like
"get_user_ips_default_Mapper|UserIpMap|users". This string changes when the
permissions are for a different user.
Clearing all caches shouldn't be a problem in a test context.

Repository statistics
=====================
Kallithea has a *repository statistics* feature, disabled by default. When
enabled, the amount of commits per committer is visualized in a timeline. This
feature can be enabled using the ``Enable statistics`` checkbox on the
repository ``Settings`` page.
The statistics system makes heavy demands on the server resources, so
in order to keep a balance between usability and performance, statistics are
cached inside the database and gathered incrementally.
When Celery is disabled:
On each first visit to the summary page a set of 250 commits are parsed and
added to the statistics cache. This incremental gathering also happens on each
visit to the statistics page, until all commits are fetched.
Statistics are kept cached until additional commits are added to the
repository. In such a case Kallithea will only fetch the new commits when
updating its statistics cache.
When Celery is enabled:
On the first visit to the summary page, Kallithea will create tasks that will
execute on Celery workers. These tasks will gather all of the statistics until
all commits are parsed. Each task parses 250 commits, then launches a new
task.
