Title: Migrate to groovy templates from Spring 4.1

Update `GroovyTemplateAutoConfiguration` to use Spring 4.1 Groovy
Markup Template infrastructure instead of Boot's.

Important changes:
* removed checkTemplateLocation from `GroovyTemplateProperties`
* removed support for Groovy's SimpleTemplateEngine

Fixes gh-1552
