webadmin: Adjust DashboardDataServlet query cache handling

Switch dashboard query cache from running at set intervals to waiting for
a set amount of time between the completion of one and the execution of
the next. Additionally, if background cache update is enabled (the default),
cache evistion isn't used. If the cache update is disabled, then cache
eviction is enabled - allowing the queries to be cached for at least a
short time.
