Issue XD-2948: Document how to specify custom-modules location via Environment variable.
It is possible to specify the location of custom modules via the environment variable {{XD_CUSTOMMODULE_HOME}} which is provided by Spring Boot property key derivation mechanism (in this case derived from {{xd.customModule.home}}). This allows a user to specify a custom modules location that survives a complete wipe of spring-xd installations.
