Update to provide docker based replication

[KennethAdamMiller]

There is a problem: after you run init.sh to initialize a replica, the project all builds and comes together but when you try to run it, it just says:

vm-escape: [!] failed to find usable chunks

I don't know what I'm doing wrong. Please merge this PR and run init.sh. I think the very last line there fails where I tried to run the script from init, but you can just docker run a bash shell and then call run_vm_escape.sh. Don't forget --device /dev/kvm for that, so it should be:

#docker run --device=/dev/kvm -ti vm_escape ./run_vm_escape.sh # <== this line from init.sh fails, so run:

docker run --device=/dev/kvm -ti vm_escape /bin/bash

and then in the shell run:

run_vm_escape.sh

This will give you another shell, nested QEMU inside docker, at which point you can run vm-escape to see the failure I reported above.
