Enhancement: kill switch

[faxm0dem]

It would make sense to be able to cancel an ongoing query, if any of the following apply:

• the user closes his browser window/tab
• the user runs another query by clicking on any icon which runs a query
• the user clicks on an explicit "cancel" button

There is no method for killing Elasticsearch queries. The best we can do is not go to the next index in the case of panels that are able to query indices in a sequential manner, which already happens. There's an elasticsearch ticket here that mentions the ability to kill queries:

elastic/elasticsearch#4329

Hi @rashidkpc @tbragin , the task management API is now available. this could likely be reopen? Would be cool Kibana automatically issued cancellations when switching dashboards.

@stacey-gammon @alexfrancoeur ^^ Not sure if we are already tracking something similar in another open issue?

There's this: #14544 that I found for discover, but I couldn't find one for dashboard specifically.

I've had a few different discussions with @epixa about utilizing the task management API across Kibana. In our last discussion, I believe we decided to fix a longstanding issue with the kibana_timeout setting first (#5608?). @epixa should we re-open this issue or create a new one to utilize the task management API across Kibana?

@alexfrancoeur Given the nature of Kibana today, I don't think one issue can cover this. I think filing discrete issues for specific circumstances, like #14544 is the best way to handle it. I wish we could handle this globally, but our search and routing abstractions are just nowhere near capable of doing that for all the features of Kibana. It sounds like the specific need brought up now is to cancel requests when leaving a dashboard, so I recommend creating an issue for that.

thanks @epixa I had thought of a number of other ways in which we could utilize this new API. I'll open a few issues later this week, including cancelling requests when leaving a dashboard.

Separated this request and others into a few issues: #17265, #17844, #17845, #17846
