MongoOptions introduce a well typed HostAddress type that tracks
the correct shape of a host's address depending on its type.
The MongoClientOptions type inherit from node's TLS and Socket options
and use our allow list of options to maintain a connection between the
types and programmatic processing of options. The hierarchy of options
from MongoClient > Topology > Server > ConnectionPool > Connection have
been corrected and clarified for responsibilities.
