Trigger build on tag plugin

[Cristian Morales Vega]

https://github.com/jenkinsci/github-branch-source-plugin/pull/158/
makes Jenkins aware of tags. Once discovered, you can go to
https://<jenkins>/job/<job>/view/tags/job/<tag>/ and trigger a build,
but I would want the build to be automatically triggered.

As per https://github.com/jenkinsci/github-branch-source-plugin/pull/158/#issuecomment-331849109
the behaviour is expected, requiring another plugin to change it. Some
people have even created such a plugin (e.g.
https://github.com/AngryBytes/jenkins-build-everything-strategy-plugin)
but I can't find anything in https://plugins.jenkins.io/. With tag
discovery support being 5 years old already, surely there is one, and
I'm just unable to see it?

Sorry, never mind,
https://github.com/jenkinsci/basic-branch-build-strategies-plugin/blob/master/docs/user.adoc
Somehow, the broken link in
https://plugins.jenkins.io/basic-branch-build-strategies/ made me skip
it on the first pass.
