[REQ][Handlebars] Move all mustache templates in resource folder to new mustache subfolder to better support multiple template Engines

Created by: lindgrenfredrik

Is your feature request related to a problem? Please describe.

Currently all templates are located in resources folder and all languages point to them there If choosing to run different templating engine and provide those templates would today have to live in same folder as current mustache template. This solution would make a clutter of files for every language that has supports multiple templating engines.

Describe the solution you'd like

make a new substructure in resources folder for mustache templates matching identifier of the templating engine Then new templates for other templating engines can be places in parallel folder structure related to their identifier (i.e. new folder for handlebars templates)

Describe alternatives you've considered

Add new info to Templating engine related to "folder offset" to find templates for that particular templating engine
