[Plugin] HTTP notification should use context

[LaurenceJJones]

What happened?

Whilst debugging #2619 the http plugin does not use the provided context so the request is not cancelled once the timeout is reached.

What did you expect to happen?

The http request to be cancelled when the timeout is reached.

How can we reproduce it (as minimally and precisely as possible)?

Will provide debugging environment for the #2619 and it will simulate the behaviour.

Anything else we need to know?
