Configurable location of entire .grails directory

It would be great if there was a way to move the entire .grails folder as opposed to just the .slcache directory because of the way some companies configure corporate laptops. This improvement proposal is for an environment variable that can be used to set the location for the entire .grails folder to anywhere besides the default (user's home directory). The environment variable could be called something like GRAILS_CACHE, GRAILS_CACHE_DIR, GRAILS_WORK or GRAILS_WORK_DIR. This is related to GRAILS-8059 (custom .slcache directory location) but extends it to the entire .grails directory.
