This patch adds the necessary release structure to build and deploy
the virtual coach package (hbp-nrp-virtual-coach) and the initial
features of:

- logging into OIDC as a given user
- retrieving the experiment list from a given backend (e.g. dev, staging,
  local, or other custom defined in config.json)
- retrieving a list of running experiments and details
- retrieving a list of available servers
- launching an experiment with given configuration on any or one specific
  backend server
- play/pause/stop functionality for a launched experiment

It also includes full test and code coverage and has minimal dependencies
on the rest of the platform packages at this point.
