Description
The cancel plugin creates a canceling context for each request. It adds a timeout that gets triggered after 5001 milliseconds.
The 5001 number was chosen because the default timeout for DNS clients is 5 seconds, after that they give up.
A plugin interested in the cancellation status should call plugin.Done()
on the context. If the
context was canceled due to a timeout the plugin should not write anything back to the client and
return a value indicating CoreDNS should not either; a zero return value should suffice for that.
