adding support for barrier-kvm

[Akilan1999]

Adding support for issue #6

This is done by integrating support to run Barrier KVM client on the side sharing the screen. At the current implementation only the
server running the laplace binary can allow the remote machines to control the screen.

The machine that wants to control the screen needs to either be:

• Same network as the server
• Needs to have an IPV6 address
• Needs to have an public IPV4 address

Setup videos

• Server Side: WebRTC screen share with remote keyboard and mouse connection (Part 1)
  

• Client Side: WebRTC screen share with remote keyboard and mouse connection (Part 2)
