[Docs test] Config settings mock-up

[kilfoyle]

Summary

Please don't merge!

This is a mock-up of how a list of Kibana settings can be rendered in Asciidoc from a YAML source file (kibana-config-settings.yml) that contains a list of all public Kibana configuration settings and their properties.

1. kibana-config-settings.yml → Perl script: perl parse-settings.pl → kibana-config-settings.asciidoc (contains Asciidoc-formatted settings snippets).

2. alert-action-settings-new.asciidoc (replacing the original alert-action-settings.asciidoc content with simple include statements) pulls in those snippets, and from that source file we generate the HTML public docs.

Note: If you want to run the Perl script you need to update the variables at lines 18 and 19 to your local path. For example: my $sourcedir = '/Users/kilfoyle/repos/kibana/docs/settings-gen/source'; my $asciidocdir = '/Users/kilfoyle/repos/kibana/docs/settings-gen/source/';
