Support for custom YAML tags

Some utilities extend YAML syntax with custom tags. For example JJB introduces “include” tags, http://jenkins-job-builder.readthedocs.io/en/latest/definition.html?highlight=!include-raw#module-jenkins_jobs.local_yaml

YAML linter fails on provided examples. Eg here

- job:
  name: test-job-1
  builders:
    !include: include001.yaml.inc

it says unknown tag <!include:> at: '4,5'.

According to documentation, currently there is no way

• to ignore some warnings, or
• to extend YAML schema with additional tags.

But custom tags are language feature, see http://www.yaml.org/spec/1.2/spec.html#id2761292 , Example 2.24. Global Tags. This document causes errors too:

%TAG ! tag:clarkevans.com,2002:
--- !shape
  # Use the ! handle for presenting
  # tag:clarkevans.com,2002:circle
- !circle
  center: &ORIGIN {x: 73, y: 129}
  radius: 7
- !line
  start: *ORIGIN
  finish: { x: 89, y: 102 }
- !label
  start: *ORIGIN
  color: 0xFFEEBB
  text: Pretty vector drawing.

Could you implement this spec or add some workaround?
