feat: dockerize dcr

[qascade]

Description

As of now, if some one wants to test run dcr, he has to use a Linux machine and has to go through the hassle of installing all the dependencies. I want to make it easier by allowing the demonstration to run on any host.
Prepare
Dockerize dcr and add ENTRYPOINT of dcr run -p sample/init_collaboration. It's better to update docs on how to interact with containerized binary.
