workflow - being able to specify some external input

[hans-d]

Describe the Feature

want to provide some external input to a workflow file. Eg for which terraform action it needs to execute.
Now all is hardcoded, this would allow for using the same code for plan/deploy.

Expected Behavior

like ansible-playbook -e option, including having a default

eg atmos workflow tf/alll -e cmd=deploy and atmos workflow tf/alll (this one defaulting to plan

Use Case

Running workflow manually to see changes, eg for things that are not deployed by spacelift yet but need to be deployed manually. This allows for a first review, before execution. Without having to duplicate all the workflow commands and steps

Describe Ideal Solution

like ansible-playbook -e option, including having a default

Alternatives Considered

duplicate lots of code in the workflow
