tests: skip reading Git system and global configuration in test_vcs_operations
The parent changeset reduced the dependency on global configuration and made it
possible to run tests without any global git configuration. But it is still
unfortunate to even look at the global configuration when running tests.
Global configuration is already disabled for Mercurial by setting HGRCPATH.
Now do something similar for Git. According to the git man page,
GIT_CONFIG_GLOBAL and GIT_CONFIG_SYSTEM set to /dev/null will make Git skip
reading the configuration files on all platforms.
Note that the GIT_CONFIG variables were introduced in Git 2.32.0, so this will
not work with all the Git versions supported by Kallithea.

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