Create template for email responses from service desk

Problem Description

The standard email response provided by the service desk when a new ticket is created is not suitable for all configurations or use-cases. There are issues with the lack of localization and the idea that organizations cannot add their own information.

Examples:

As a support organization using the Service Desk, we need a way to provide customized information in the email response when a ticket is created.

As a support organization using the Service Desk, we need a way to respond to our customers in our native language.

As a community member, I want to submit a issue via email and see a response in my native language from a recognizable address.

Proposal

Provide a means of allowing an email response template that allows organizations to personalize the response generated when a new service desk ticket is initiated via email.

The MVC for this will be to allow for the standard email text to be customized.

This will be done by allowing users to create markdown templates that will be stored in a known location within the repository similar to issue and merge request templates.

Future improvements will be tracked under &1990.
