BP-41 Add flag to enable/disable BookieAddressResolver (#3356)

### Motivation

With BP-41, the BookKeeper client now needs a request to ZooKeeper to resolve the address from each bookie ID.

In the following document, there is a description of the flag ~`enableBookieAddressResolver`~ `bookieAddressResolverEnabled` for disabling this feature by regarding the bookie ID as an address or hostname, but it seems that this has not been implemented yet.
https://github.com/apache/bookkeeper/blob/master/site3/website/src/pages/bps/BP-41-bookieid.md

I implemented this because I want this flag to reduce the number of requests to ZK.

### Changes

Added a flag named ~`enableBookieAddressResolver`~ `bookieAddressResolverEnabled` to the client configuration. If this flag is false, use `BookieAddressResolverDisabled` instead of `DefaultBookieAddressResolver` as the address resolver for bookies. `BookieAddressResolverDisabled` regards a bookie ID to be in legacy format, i.e. "address:port" or "hostname:port", and returns the address of that bookie without access to ZK.
