DrillUserProperties has a _map_ and a _vector_. The _vector_ stores the
actual prop key/value pair and in _map_ we store the prop key and corresponding
bits indicating _USERPROP_FLAGS_SERVERPROP|USERPROP_FLAGS_STRING_. This is
later used in handshake message to filter out the properties passed by client
and the one which is needed for server side to send along with handshake msg.
