[table service] add a bookie registration based grpc name resolver

[sijie]

Descriptions of the changes in this PR:

Motivation

Table service is using grpc name resolver to figure out the alive servers serving table service.
Currently it is using default dns name resolver. In the context of Pulsar, since brokers talk
to bookies via zookeeper service discovery, it is making sense for brokers talk to table service
via zookeeper service discovery. So this PR is to add a bookie registration based grpc name resolver.

Changes

Implement a bookie-registration library based grpc name resolver.

This PR is based on #1841 since it requires RelectionUtils available in bookkeeper-common instead of bookkeeper-server module.

@merlimat : added this zookeeper based grpc name resolver for allowing a smooth upgrade in pulsar without adding hassles at configuring dns for accessing table service.

[sijie]

rebased to master after #1841 is merged.
