Purge room API
==============
This API will remove all trace of a room from your database.
All local users must have left the room before it can be removed.
The API is:
```
POST /_synapse/admin/v1/purge_room
{
"room_id": "!room:id"
}
```
You must authenticate using the access token of an admin user.
