Abort pending request

[igaloly]

The problem
There's no ability to cancel/abort a request that is pending and hasn't resolved yet

Use case

• The user selected some parameters and the fetch began.
• The user regretted his choice.
• The user changed the parameters and another fetch began.
• The second fetch resolved and data is displaying, the user is happy.
• First fetch resolved, and because it was heavier, it took a longer time
• The old unwanted data is being displayed, the user is sad.

Works, but

• You need to generate id yourself so that you will know what's the id of the current fetch
• You need you to use methods without an abstraction, that it seems like, are not intended to be used by the end-user ( generateQueryId, fetchQuery, stopQuery etc )

Works, but

• You need to use a method, it seems like, not in the way it intended to be used
• You need to promisify the subscribe and generally, work in a completely different way compared to simple query / mutation

Thoughts
It seems like the first solution is much more suitable, but a good abstraction should be implemented

vue-apollo doesn't handle making requests, it's apollo-client itself.

I understand.
But there is already such a capability implemented by apollo-client.
The problem is that there's no appropriate abstraction for this in vue-apollo's side.
We need to be able to the get the queryId of a pending query by its name ( or any other way ), and a method such as 'stopQuery' that'll get the id and will kill it.

@Akryum
Also, what do you think about the implementation of canceling pending requests when the component destroyed?
