[choir] Explore Ansible capabilities to orchestrate nodes

[Gelassen]

User story:

As a developer I want to easily deploy and scale up infrastructure, preferably in 1-3 clicks.

Tech description:

Bash and npm scripts helped a lot with automatisation of the process. Planned migration to Docker compose should help go even further with automatisation of the whole ecosystem. Although, it is already known Docker is not a virtualisation technology and could not be considered as a full replacement of the VM. It breaks isolation environment for some cases, e.g. db volume mapping, which may be crucial for such tasks as a private chain deployment.

Ansible is not a virtualization or a containerization technology at all, but it is still automatisation tool which might be more handy in some cases rather than docker compose. The aim of this task to explore the Ansible capabilities and, in the positive case, define steps to utilise the Ansible for project.

Current important task is orchestrate private chain nodes with secure way of passing passwords,
