feat: Support Multiple Build Steps With Different Captains Yamls

[therynamo]

Is your feature request related to a problem? Please describe.
Users may want to have multiple build steps using different configurations of Captain's Log. This will work if you inline it, but it won't work if you use .captains.yml.

Describe the solution you'd like
We should find a way where we can support this using .captains.yml. That would most likely look like convention, or perhaps a k/v association.

Describe alternatives you've considered
