Remove spring-integration-gemfire module

Starting with Spring Data 2022.0.0 there is not going to be GemFire (Geode) support
directly from Spring team

A source code of the `spring-integration-gemfire` is moving to Spring Integration Extensions
from where community may consider to pull it and support in their own manner
