Utility to install a server via Redfish

This update introduces the implementation for a docker container named
'rvmc', standing for Redfish Virtual Media Controller, which executes a
python file that imports the open source redfish-python-library used to
establish a secure Redfish communication session with a Redfish
supported Board Management Controller to insert a URL based ISO image
into its Virtual Media CD/DVD device so that on that server's next
reboot will boot and install that image.

This container supports single and multi target configuration files with
IPV4 and IPV6 BMC addressing.
