Adding the refresh parameter to the list of subscriptions

[agoncal]

Purpose

When displaying the list of Azure subscriptions, you can get old ones that do not exist anymore, that's because the subscriptions are cached locally. Adding the refresh parameter allows the subcriptions list to be refreshed with the ones on the server.

Please do not reformat the document along with the change as it makes it hard to see what really changed.

On the note of the refresh parameter I think we should just add it to the existing command line and not add a new paragraph for it.

Note we also need a corresponding issue so folks can just keep track of what changed by looking at our issues.

Here is the issue : #140

Yes, we can just leave the command with the refresh parameter.

As for the formatting, you are right. When writting in Markdown or Asciidoc I usually write one sentence per line so merging and diffs are easier (but not when you reformat everything ;o)
