CLI arg reorganisation

[jayvdb]

I am wondering whether it would be reasonable to re-organise the CLI args a bit, hopefully adding more clarity.

Existing CLI args would be supported, but some might be deprecated.

• db - Operations that configure/touch the database
  • init
  • clear
  • delete
  • migrate
  • rollback
• migrations - Operations on the existing migrations (excluding "current")
  • list
  • backend (as this hasnt been released yet, the top level "backend" could be removed)
    • add
    • remove
    • list
  • collapse
  • embed? - doesnt really belong here, as it doesnt modify existing migrations)
  • make (make-migration)
  • regenerate
  • detach (detach-migration)
• rust
  • embed?
• state (not sure what to call this: operations related to "current" migration and other state files not elsewhere classified)
  • clean

#230 complicates the separation between migrations and state

[Electron100]

I support the idea. Give me another day or two to think about whether I have any strong opinions on the specifics.
