docker: add base toolset for building images

This patch brings a base toolset for building official Docker images for
Tarantool 3.0+ version.

Toolset components:

1. Dockerfile for building Docker images (based on Ubuntu 22.04)
2. Docker entrypoint script (docker-entrypoint.sh)
3. Default Tarantool config (default-config.yaml)
4. Auxiliary tools for checking Tarantool instance status and connecting
   to admin console
5. Example of a basic Tarantool cluster that can be started via Docker
   Compose (a tool for running multi-container applications)
