[PATCH v2 4/5] tests: remotehost: ssh allow to skip user

[Janusz Dziedzic <janusz.dziedzic@xxxxxxxxx>]

Allow to skip user name when we run
ssh user@hostname.

We can specify user name in .ssh/config
and simplify using network name spaces
mapped per user.

Eg. of .ssh/config

 Host localhost
    HostName localhost
    User root

 Host test1
    HostName testpc
    User wlan1
