feat: Introduce queue based live stat refresh

[keriati]

Goals:

• Reduce the update interval of the tiles in general to avoid increased server load.
• More reliable way to suspend and resume updates.
• Limit the number of active requests to 1 / sec even if a lot of live tiles are added.
• Remove jquery dependency

Queue feature:

• A queue is created that is processing live stat refresh jobs every 1 second
• update jobs are adding themselves to the queue
• successful jobs are adding themselves back to the queue
• failing jobs are not added back to the queue
• when the window visibility changes to hidden the queue is suspended
• when the window visibility changes to not hidden the queue is resumed
• at page load all jobs are executed instantly 1 time

Intervals:

• jobs with dataonly attribute: 30 sec always
• jobs with that are reported active: 5 sec
• jobs that are not active: 30 sec
