Rishi Gupta 20255e48a4 analytics: Change messages_sent_to_stream to a daily stat. ...

Analytics database tables are getting big, and so we're likely moving to a
model where ~all stats are day stats, and we keep hourly stats only for the
last N days.

Also changed the name because:
* messages_sent_* suggests the counts (summed over subgroup) should be the
  same as the other messages_sent stats, but they are different (these don't
  include PMs).
* messages_sent_by_stream:is_bot:day is longer than 32 characters, the max
  allowable length for a BaseCount.property.

Includes a database migration to remove the old stat from the analytics
tables.
