Add argument descriptions to all "add constraints" functions

[clizbe]

What and Why

The functions in the constraints folder should describe the arguments for the functions.
These files are:

• capacity.jl
• consumer.jl
• conversion.jl
• energy.jl
• hub.jl
• investment.jl
• storage.jl
• transport.jl

Here's an example of the lack of argument documentation. What are the Ai, Ase, Fi, etc arguments?

Thanks! This action was identified in the refactor EPIC, but It had not issue assigned (until now 😝). I'm adding the issue to the EPIC 😄

The arguments of all these functions should have been simplified to only require properly named arguments (connection, model, etc.). The docstrings will still need to be updated after the bulk of the refactor is done, but the arguments should now be clearer.
