Simplify SystemHookUrlValidator to inherit from PublicUrlValidator
Refactor specs to move out shared examples to be used in both
system hooks and public url validators.

Updating security/webhooks.md to match new behaviour
as well as drying up few specs to extract shared
examples

This MR adds new application setting to network section
`allow_local_requests_from_system_hooks`. Prior to this change
system hooks were allowed to do local network requests by default
and we are adding an ability for admins to control it.

Improve job log rendering performance

See merge request gitlab-org/gitlab-ce!31262

Currently we write out empty CSS classes (`class=""`) every time we
create a new tag. This adds 9 unnecessary bytes per span element. In a
recent trace, I have counted 11950 span elements. So we transported 105
unnecessary kilobytes!

Fix GC::Profiler metrics fetching

See merge request gitlab-org/gitlab-ce!31331

Previously, both InfluxSampler and RubySampler were relying on the
`GC::Profiler.total_time` data which is the sum over the list
of captured GC events. Also, both samplers asynchronously called
`GC::Profiler.clear` which led to incorrect metric data because
each sampler has the wrong assumption it is the only object who calls
`GC::Profiler.clear` and thus could rely on the gathered results between
such calls.

We should ensure that `GC::Profiler.total_time` is called only in one
place making it possible to rely on accumulated data between such wipes.

Also, we need to track the amount of profiler reports we lost.
