Testnet deployment

[aleksandrliamov]

Hi
We are trying to deploy your marlin testnet. We started from that page then that page. The single readme which we found was in the root of the repo and it does not cover "bsc stack".
We configured gcloud with pulumi, it is up and running but we tried to deploy something with ansible and it was unsuccessful.
Two active issues:

1. Ansible-playbook fails because there is no "gcp_role_relay" host defined anywhere.
2. It is not clear should we build relay/beacon from sources in OpenWaver repo or you have existing binaries

We're moving to using https://github.com/marlinprotocol/marlinctl as the preferred method of deployment since its much simpler, will be updating the ansible scripts here to do the same.

But for now, this is probably the latest version. And to answer your queries:

1. The hosts are pulled in through dynamic inventory scripts. You might be missing a few configs (like credentials). Ref: https://docs.ansible.com/ansible/latest/scenario_guides/guide_gce.html
2. Yes, you need to build them from sources yourself. Once we move to marlinctl, this wouldn't be an issue since it uses pre-built binaries.
