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.
Also, is the result of `"Get-SCVirtualMachine -Name \"{}\" -VMMServer $scvmm_server` something we can cache rather than getting it on every call?
