  - teststeps: Improvements of step driven TC
    
    This patch adds support of access to VMs deployed automatically
    by deployment scenario (e.g. pvp, pvvp4, etc.). It also modifies
    filter for checking output of executed commands to correctly
    handle different end of line encodings (i.e. \n vs. \n\r).
