Printing port when connecting by Unix domain socket

[margdoc]

When connecting to the scylla node using the following command:

cqlsh /home/margdoc/Workspace/scylla/workdir/0/cql.m 

the first line of the output is:

Connected to  at /home/margdoc/Workspace/scylla/workdir/0/cql.m:9042

cqlsh prints the default port on which it connects to the scylla node but doesn't use it when connecting by maintenance socket.
