[Mozilla Enterprise] Documentation of new Policy feature

[Klaus Hartnegg]

I have a few suggestions:

The page
https://support.mozilla.org/kb/customizing-firefox-using-policiesjson
should contain info about
- Windows
- Group Policy
- interaction between mozilla.cfg, policies.json, and Group Policy
- future plans (will ESR receive updates to this?)
- where to send suggestions for additional policies
- future of autoconfig aka mozilla.cfg
- details about the ESR-or-domain requirement
- download-links for the template files
- cck2
- https://addons.mozilla.org/firefox/addon/enterprise-policy-generator/

The page
https://wiki.mozilla.org/Firefox/EnterprisePolicies
should point directly to
https://support.mozilla.org/products/firefox-enterprise

the page
https://support.mozilla.org/products/firefox-enterprise/autoconfiguration-enterprise
should tell that this will become deprecated.
