Enable listing builds for multiple build types

[0xfad1]

Hello,

1. As a user building models for different services, I would like to specify one or more build types in the build command.
2. The display should return results either alphabetical or as requested by the user
3. As a power user, I would also like to specify a default build type in the central config file so I don't have to type --build-type

Current behaviour

mix builds:list -P 000 --build-type=asr,nlu --no-truncate Error: Expected --build-type=asr,nlu to be one of: asr, dialog, nlu ›   See more help with --help

Desired behavior:

mix build:list -P 000 --build-type=asr,nlu -> displays builds for both asr & nlu mix build:list -P 000 -> retrieves all builds for all build types specified in config file

Some thoughts:

• The endpoint that list builds currently accept a single build type. However, the command could take care of making the n calls to that endpoint to cover the n build types.
• Environment variables (which can also be defined through a .env file file) enable providing defaults for project ID, organization ID and a few others. We should consider adding build type to that if it can be done consistently across all commands that accept a build type.
