* Ensure appservices can auth as users in their namespaces
Currently in Dendrite appservices can only auth as a user if the user was created by said appservice. This does not align with the appservices spec which specifically says:
> The application service may specify the virtual user to act as through use of a user_id query string parameter on the request. The user specified in the query string must be covered by one of the application service’s user namespaces.
https://matrix.org/docs/spec/application_service/r0.1.2#identity-assertion
In the case that a user has been created for example via manual registration but belongs to an appservice namespace, the current functionality does not allow appservices to auth as them. This PR fixes that by replacing the appservice ID check with a check against the appservice namespace.
This also matches Synapse functionality, which I confirmed to allow appservices to auth as a user in their namespace, irregardless of how the user was registered.
* Also allow appservice itself to auth with user_id
Appservice user_id + access token check needs to work both when user_id is the appservice and when appservice has the user in their user namespace.

* WIP: Eagerly sync device lists on /user/keys/query requests
Also notify servers when a user's device display name changes. Few
caveats:
- sytest `Device deletion propagates over federation` fails
- `populateResponseWithDeviceKeysFromDatabase` is called from multiple
goroutines and hence is unsafe.

* Add PerformDeviceUpdate and fix a few bugs
- Correct device deletion query on sqlite
- Return no keys on /keys/query rather than an empty key

* BREAKING: Make eduserver/appservice use userapi
This is a breaking change because this PR restructures how the AS API
tracks its position in Kafka streams. Previously, it used the account DB
to store partition offsets. However, this is also being used by `clientapi`
for the same purpose, which is bad (each component needs to store offsets
independently or else you might lose messages across restarts). This PR
changes this behaviour to now store partition offsets in the `appservice`
database.
This means that:
- Upon restart, the `appservice` component will attempt to replay all
room events from the beginning of time.
- An additional table will be created in the appservice database, which
in and of itself is backwards compatible.
* Return ErrorConflict
* Make userapi responsible for checking access tokens
There's still plenty of dependencies on account/device DBs, but this
is a start. This is a breaking change as it adds a required config
value `listen.user_api`.
* Cleanup
* Review comments and test fix
