Azure provisioner supply groupName or mailNickName JEXL via Attribute value/string

To create a new transformation of the group and email JEXL naming, I have to create a whole new set of parameters in grouper-loader.properties, and create another attribute to connect them. I then have to bounce the daemon container to make those take effect. I now have several different "profiles" to satisfy customer requirements. I feel like this would be more flexible if I could just specify the JEXL within a folder's assigned attribute, say "etc:attribute:o365:mailNickNameJexl". Then tell the config to use the value supplied in this attribute, rather than the one hard-coded in the grouper-loader.properties. This would allow me to centrally manage fewer attributes/configs, yet allow flexibility to the distributed admins to control the naming conventions needed for their folders to sync.
