node/service/src/lib: Do not spawn authority discovery on sentries (#1835)

Browse Source 
* node/service/src/lib: Do not spawn authority discovery on sentries

The notion of sentry nodes has been deprecated (see [1] for details).
Support for sentry nodes in the `client/authority-discovery` module has
been removed.

This commit adjusts the instantiation of the authority discovery worker
accordingly, only spawning the module on authority nodes.
