Get changed issues by sonarqube web-api

@ganncamp, from an audit perspective, I really believe this feature is important.

Right now, I and other users cannot develop a feed to off-line loggers reliably. Having API which allows pulling records sorted and filtered by the update date seems to be a basic, must-have sort of capability. I’ve added a suggestion in the past (below), but would really like to see if we can get some support generated around this.
