Virtual media page

Adds page to manage virtual media devices. User selects file
and pushes 'start' button to establish websocket connection.
nbdServerService added to provide ability for user to navigate
away from the page and return with the ability to see the current
active sessions.

Currently only supports 1 Virtual Media device.

Resolves openbmc/phosphor-webui#40

Tested: uploaded ubuntu image file, started the connection  and
  mounted virtual media device from host console. Able to see Ubuntu
  image file. Also uploaded file and navigated away from the page,
  checking that the websocket remained open and was sending /
  recieving messages.  Finally, tested that when connection
  was stopped, 'USB disconnect' log was present in host console.
