Description

Currently, Alerts UI sends a query request to the REST API every time the user 

• add new filter
• clear filters
• change time range

This behavior keeps the list of alerts and the state of the filtering in sync: every time the filter changes the visualized data change with it.

The drawback of this behavior is it fires multiple query requests while the user tries to set up a more complex filter.

The following scenario:

1. clearing the current filter
2. changing the time range
3. adding a filter for ip_src_addr
4. adding a filter for source:type
5. pressing the query button

leads 5 queries instead of one. In the case of large data sets, this could lead to unnecessary load and UI glitches (results update the alerts table with partially filtered data).
