Acknowledge multiple problems at the same time

[ombr-lcalseverini]

In the Zabbix Problem panel, when I want to acknowledge multiple problems, I have to go through each problem, one by one.
In Zabbix Web, I can actually acknowledge multiple problems by mass updating.

I want that feature added to the Problems panel, so people that only have access to Grafana can still acknowledge a lot of problems at the same time.
