Visual Studio: Add Action "Get Query Results"

[brucephenry]

As a Flow creator,
I want to be able to get the results of a saved query in TFS (or VSO, or VSTS, whatever the heck the cool kids are calling it these days),
So that I can do things like:

• Make a summary post to Teams
• Send individual email reminders to people who are listed in the results to follow up on their items

I'll know this is done when:

• I can specify a saved query to execute
• The name of the query is available in Flow dynamic content
• The total items returned is availalbe in Flow dynamic content
• Each column specified in the query is available in Flow dynamic content
  OR
  All columns are available in Flow dynamic content
• I can branch on ZERO items returned to trigger exception handling scenarios
