Issue 12183 - Remove unnecessary test dependencies from build

[yuri1969]

A quick attempt to resolve #12183. It was based on a Gradle dependency listing obtained from a 5.1.2 REST application.

Aimed to remove just the test-related dependencies.

• Removed unused groovy-ant from grails-plugin-i18n.
• Removed unused junit from grails-plugin-url-mappings.
• Upgraded cache plugin to solve gpars-related issues.
• Moved spring-test to the test source set.

Notes:

• Dependency constraint (marked as (c)) should be fine.
• BOM dependencies should also be fine.
• GrailsWebMockUtil was moved to the grails-test project - is it a correct location?

@yuri1969 , @puneetbehl ,

GrailsWebMockUtil is not accessible now because it moved from util to test.
I am using this file to change the locale for localization in a cron job.

Is there an alternative to this? Please suggest.

@yuri1969 I have reverted this change and will do a Grails 5.1.5 release as this seems to break applications updating from 5.1.x. I think we should move this change to 5.2.x and have clean upgrade notes.

@manishkbharti You should add the following dependency to build in order to resolve this:

testImplementation("org.grails:grails-test:${grailsVersion}")

Thank you @puneetbehl
Sure I'll use this dependency.

@puneetbehl You are right. The PR should go to the 5.2.x branch. Having a doc note at least describing impact of the scope change for org.springframework.spring-test would be nice. Would you do it?
