`DefaultService` serves as a useful no-op service to cut down on bloat when
implementing new Services. This means we can add more methods more freely to
the interface of `Service` without bogging down the Service implementation.
`Poller` is an interface which contains a polling interval and a function to
invoke. This will be used for RSS feeds.
Implemented a stub `RSSService`.
Removing a repo entirely from a service will now remove the webhook in the
`PostRegister()` function. This function is still within the `configureService`
critical section to prevent another request for the same service racing with
the cleanup process.
We only use it for making webhooks (to determine which GH account to load up).
We need it to be optional for the global GH bot to work (which has no account
and uses the account of whoever issued the !command to do the work).
Previously, we would notify `Services` based on matching the `room_id` of the
event with a list of `RoomIDs()` which the service returned.
Now we notify `Services` based on matching the `user_id` of the client listening
for events. This means that the service will receive more events because there
isn't a filter on a set of room IDs.
This is required in order to implement "auto-join on invite" semantics for
Services, as the room ID is not known at that point in time.
We don't put any restrictions on the format of the Service ID so we need to
base64 it to prevent potentially losing data when it is inserted as a path
parameter (e.g. due to weird escaping rules).
Also, only remove webhooks if there was an old service to begin with.
Also start including unauthorised webhook creation semantics, though not
finished yet. Change the config format of `JIRAService` to make more sense
and allow multiple realms per room.
