Since we've got rid of the concept of Complimentary with the Custom
Prices work, we're removing the 'comped' status from members. This
involves a migration for existing members, a schema update for the
validation, and a bump to members-api to no longer use the 'comped'
status for new members.
We also update the aggregation of the MemberStatusEvent to consider the
'comped' status as 'paid', and that there are 0 'comped' status events
in the database.
We can consider a migration for this data in the future, either adding
new status events moving from 'comped' to 'paid', or by modifying
existing status events. However both of these are very difficulty to
write a down migration for, and might be best saved for a major version.
- @tryghost/members-api@1.7.0 is the version that includes the required
changes, however we have already bumped to 1.8.0 in Ghost

* Updated members_status_events table
By replacing the `status` column with a `from_status` and `to_status`
column, we are able to track the changes between multiple statuses
easier, and accumulate the data. e.g. the delta of paid members in a
given time range is the sum of the `to_status` columns set to 'paid'
minus the sum of the `from_status` columns set to 'paid' within that
time range
* Updated MEGA to handle addition of 'comped' status
With the addition of the 'comped' status, we need to ensure that MEGA
will still send emails to the correct recipients. I've opted to use an
"inverse" filter, as that is the intention of the free/paid split in
MEGA - as far as MEGA is concerned, "free" is the opposite of "paid"
* Updated customQuery for MemberStatusEvent
With the `status` column replaced with `from_status` and `to_status`
this allows us to fix and update the customQuery to correctly accumulate
the data into deltas over time, broken down by day.
* Populated members_status_events table
As the table will be used to generate deltas, we need to backfill the
data so that existing sites will be able to sum up the deltas and
calculate correct data.
The assumptions used in backfilling is that a Member's current status,
is their only status.
