Using sys.exit in a management command makes it impossible
to unit test the code in question. The correct approach to do the same
thing in Django management commands is to raise CommandError.

AssertionErrors were raised when attempting to run manual comparison
tests to ensure correctness when exporting the analytics realm using
export_from_config. This was caused by this populate_analytics_db
stream being created without any subscribers, which violates an
invariant.
We fix this by simply subscribing the 'shylock' user to that stream.
This deletes the unused Subscription.notifications field and removes
it from some testing and analytics code (which should not have been
using it in the first place).
Fixes#10042.
This fixes a subtle bug where if you reran populate_analytics_db
directly, we'd end up in a weird state where memcached fetched the
"old" pre-flush UserProfile object for shylock when loading /stats,
which ultimately would result in /stats appearing totally broken.
These are no longer useful, with our spiffy new analytics framework,
and we haven't in fact been using them for some time, while the
`active-user-stats` cron job does cause regular mail from cron.
Just delete them.
Previously we showed the total number of users with an active account. This
changes it to show only the number of users that have logged in in the past
two weeks.
Groundwork for allowing stats like "Monthly Active Users".
CountStat.interval is no longer as clean a value as before, so removed it
from views.get_chart_data. It wasn't being used by the frontend anyway.
Removing interval from logger calls in counts.py is not a big loss since we
now include the frequency (which is typically also the interval) in
CountStat.property.
Originally, all the client names in populate_analytics_db started with
underscores to make it easy to selectively delete and regenerate them when
re-running populate_analytics_db.
We eventually want to merge populate_analytics_db into populate_db though,
in which case it makes more sense for them to share client names, and not
worry about the case where we run (or re-run) populate_analytics_db
independently of populate_db.
