no issue
- moves members stats generation for the admin graph from the client to the server
- outputs a basic totals count across a requested date range of 30, 90, 365 days, or all time. See below for the response shape
- leaves heavy lifting of the counts to the SQL engines - tested on a dataset of 100k members and query performance is <100ms
```
GET /ghost/api/canary/members/stats/?days=30
{
total: 100000,
total_in_range: 20000,
total_on_date: {
'2020-04-25': 19000,
'2020-04-26': 19500,
// continues until today's date
},
new_today: 200
}
