UI action presentation

[marumer]

When presenting a command action:

• we can leave the Endpoint, Variable and Expect objects
• we should remove the API URI string
• the command payload and response should be multiline text sections
• the response will consolidate STD out and error
• we should still render the response code returned from by the backend
• the action should be validated follow the expect condition (supporting multiple body contain/not contain statements in AND)
