Better and more comments in the Rakefile
While reviewing #483 (closed) I had hard time understanding what all of our rake tasks do and what are the dependencies between them. I'd like to provide better descriptions in all the rake tasks and provide more information about:
- what the particular task does
- when the task is invoked
- does the task run on docker or on a host or both
It would be also useful to revise some of the task names and make sure they are consistent and intuitive.
