Code Issues Proposed changes

Add tests for multipath devices

Browse Source 
SSHManager.update_connection: add possibility to open new connection with
parameters, if no connection presents.

This testgroup should be run with this parameters:

    export MULTIPATH=True
    export SLAVE_MULTIPATH_DISKS_COUNT=2
    export MULTIPATH_TEMPLATE=system_test/tests_templates/tests_configs/multipath_3_nodes.yaml
