Add HostManager for host records and host tokens

controller.hosts is now a HostManager wrapping the hosts datastore, the
same way controller.users wraps the users datastore. It owns creating
hosts (moved from HostPairingManager), revoking them (moved from
ControlConnection) and signing and verifying host tokens (moved from
Controller, generateHostToken is renamed signHostToken to match
signUserToken).

UserManager gains verifyUserToken, replacing the copies of the user
token check in WsServer and routes. The WsServer copy accepted a token
without iat when the user had no tokenValidAfter; the shared check
always requires iat, which jsonwebtoken adds by default.

Host records are no longer created when a host connects, only by approving it, and the controller rejects hosts it has no record of.
Revoking a host deletes its record and note.
Plugins that keep data per host should remove it when the host is deleted.
On the controller the `update` event of `controller.hosts` gives the record with `isDeleted` set to true, and subscribers of `HostUpdatesEvent` receive the host with `isDeleted` set to true.
On the controller the `update` event of `controller.hosts.records` gives the record with `isDeleted` set to true, and subscribers of `HostUpdatesEvent` receive the host with `isDeleted` set to true.
A host that is revoked and approved again gets a new id.
## Host manager
`controller.hosts` is now a `HostManager`, like `controller.users` is a `UserManager`.
`get`, `getMutable`, `has` and `values` work as before.
Everything else on the datastore, like `set`, `delete`, `size` and the `update` event, is on `controller.hosts.records`.
The host manager also signs and checks host tokens and creates and deletes hosts:
- `controller.generateHostToken(hostId)` is now `controller.hosts.signHostToken(hostId)`.
- `controller.verifyHostToken(token)` is now `controller.hosts.verifyHostToken(token)`.
- `controller.hostPairing.createHost(name)` is now `controller.hosts.createHost(name)`.
It returns the new `HostRecord` instead of `{ hostId, token, name }`, sign a token for it with `signHostToken`.
- `controller.hosts.revokeHost(hostId, revokedBy)` deletes a host the same way `HostRevokeRequest` does.
User tokens are checked with `controller.users.verifyUserToken(token)`, which returns the user or throws if the token is invalid.
