cache: drop setup_cache_regions - tg will already have done that and coerced the types correctly

The configuration and type fixing will be invoked from make_base_app, and we
will thus not have to do it:

File "kallithea/config/middleware.py", line 31, in make_app_without_logging
return make_base_app(global_conf, full_stack=full_stack, **app_conf)
File ".../python3.7/site-packages/tg/configuration/app_config.py", line 176, in make_base_app
wrap_app)
File ".../python3.7/site-packages/tg/configurator/application.py", line 112, in _make_app
app = TGApp(conf)
File ".../python3.7/site-packages/tg/wsgiapp.py", line 49, in __init__
app_wrapper = wrapper(self.wrapped_dispatch, self.config)
File ".../python3.7/site-packages/tg/appwrappers/caching.py", line 36, in __init__
self.options = parse_cache_config_options(config)
File ".../python3.7/site-packages/beaker/util.py", line 430, in parse_cache_config_options

This will fix a py3 problem where setup_cache_regions was run *after* beaker
had coerced types, thus introducing string types in the config where beaker
expected the integers it had put there.

.. _statistics:

=====================
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.
