We are re-enabling HTTP 2 again. There has been a few bugfixes upstream
in go, and we have also enabled ReadIdleTimeout.

* Allow limiting maximum number of alerts in webhook
The webhook notifier is the only notifier that does not allow templating
on the Alertmanager side. Users who encounter occasional alert storms
(10ks of alerts going off at once for the same group) have reported
webhook receiver systems not being able to cope with the load caused by
the resulting large webhook notifier messages (the alerting rules also
contained large annotations that can't be stripped away due to lack of
templating). Reducing group size also wasn't an option, but this change
proposes to allow truncating the list of alerts sent in the webhook body
to a provided maximum length. This assumes that e.g. if a group receives
20k alerts, you really are fine only receiving 10k because you wouldn't
be able to check them all anyway.

Instead of keeping all notifiers in the notify package, it splits them
into individual sub-packages. This improves readability and
maintainability of the code.
