Rishi Gupta 0596c4a810 analytics: Enforce various datetime arguments are in UTC.
Sort of a hacky hammer, but
* The original design of the analytics system mistakenly attempted to play
  nicely with non-UTC datetimes.
* Timezone errors are really hard to find and debug, and don't jump out that
  easily when reading code.

I don't know of any outstanding errors, but putting a few "assert this
timezone is in UTC" around will hopefully reduce the chance that there are
any current or future timezone errors.

Note that none of these functions are called outside of the analytics code
(and tests). This commit also doesn't change any current behavior, assuming
a database where all datetimes have been being stored in UTC.

Rishi Gupta ebebd04587 analytics: Fix ValueErrors affecting test coverage.
Pathways that only catch internal code errors should use AssertionError so
that they are not included when computing test coverage.

Rishi Gupta 5eb5fa3f31 analytics: Change time_range to not include current day/hour.
Current day/hour will always be 0, since we haven't computed it yet for the
CountStat tables.

Rishi Gupta f8962d521d analytics: Fix uses of 'interval' in arguments and variable names.
interval refers to a time interval, and frequency refers to something that
semantically means something closer to 'hourly' or 'daily'.

Currently, interval can have values 'hour', 'day', or 'gauge', and frequency
can only have values 'hour' and 'day'.
