M$ SCVMM in mgmt_system

Working on it, seems it will be quite easy to do it. There is just only one big drawback - pywinrm cannot make domain user login with simple auth so it has to be done inside of the script which seems to be tremendously slow.
This pattern seems to be duplicated a lot, and should probably be functionalized:
`"Get-SCVirtualMachine -Name \"{}\" -VMMServer $scvmm_server | ACTION-SCVirtualMachine {}".format(vm_name, force))`
