Adding code for CrOS AV Analysis' Recording Server

Much thanks to @timkovich for authoring this code! These are the
scripts meant to setup and perform as the recording server which
will run on recording VMs set for ChromeOS AV team in LindaVista.
The function of the server is to listen for recording requests,
start recording using ffmpeg (setup in vm_prep.sh) and then upload
the files to our Google storage bucket. These files will be executed
by lab team setting up our machines.
