[FEATURE] Create an interface and MLClient for the workflow setup

[owaiskazi19]

Is your feature request related to a problem?

An interface would be needed for all the builders of the workflow to implement the same method definition. This method would help to call the specific API and return the response or store it in the global context later.

MLClient would be needed to invoke APIs from ml-commons.

What solution would you like?

public interface Workflow {

  execute()

}
