Add capability to capture tofu output as an artifact on apply

• Add capability to capture tofu output as an artifact on apply

The main toggle to enable this is using save_outputs_as_artifact when using apply.yml and apply_save_outputs_as_artifact if using the validate-plan-apply.yml

A few other options have been added to enable configuring the name of the artifact and the access level to it:

• output_artifact_name
• artifacts_access

@timofurrer i'm debating if the following inputs would be better:

• enable/disable
• artifact access level
• artifact name
• flags to pass to output (by default it might just be -json but if someone wanted to provide additional flags or other flags they can without needing to have a bunch of additional inputs)
