Added 2 new topologies:
- monolith - all database processes running in a single container using static port mappings.
- this avoids issues with docker networking when restarting after laptop hibernate.
- static port mapping makes connecting to the database from the laptop through known ports.
- instadb - all database processes running in a single container, with dynamic port mappings;
- this also avoids issues with docker networking.
- dynamic port mapping allows multiple instadb databases to run simultaneously on a single host.
See the README for details and instructions for using the different topologies.
Removed various timing gates and shifted to relying on gates internal to nuodocker.
