Dockerised or containerised environment for testing the project

[0xjjpa]

Most developers don't want to go into all the details of a wiki to understand a project (which is a pity, because in this case HOPR's is actually pretty well documented). They just want to get the hello-world example in order to test the project.

Currently, HOPR requires a bit of setup in order to be tested locally. We can probably pre-package the project into a Docker image that we can just as people to run in order to be able to get a feel of what's going on without having to do everything on the README.

We can package all the setup into an image and run a ganache-server that forwards all the RPC calls within the container while still getting the console logs. Happy to help if seems useful.
