Dockerize Helios and create install script

[bktiel]

Downloading two repositories and following manual instructions is cumbersome. Additionally, the current Helios build has several security vulnerabilities: the MongoDB installation and Helios-Bot components both assume full trust on the local machine and do not authenticate requests made. This is begging for trouble.

Two birds with one stone: Use docker compose and ansible to deploy Helios and Helios-Bot in docker containers on demand.

An install script should be made to allow for setting of parameters on initial install rather than going back and editing the configuration file.
