Unify hive into swarm

I vote the current differentiation should be unified where hive is just a set of parameters within the swarm mode. Currently for me to launch a hive, there’s not much of a simple non interactive way to do it like there is with swarm. I think hive just makes more sense in terms of developer UX as an extension of the swarm options.

Start by locating the hive and swarm launch and configuration entry points, then compare how each mode is invoked. Define how hive parameters would fit within swarm options and verify that a hive can be launched through a simple non-interactive swarm-style flow.
