Previously, spring.groovy.template.configuration properties were
bound directly to GroovyMarkupConfigurer. This meant that the
properties had no description or default values in the metadata.
It also resulted in some duplicate where a specific
spring.groovy.template property was also provided.
This commit deprecates the spring.groovy.template.configuration.*
properties in favour of specific spring.groovy.template.* properties
that are mapped to the GroovyMarkupConfigurer.
