[OPTIONAL] Enable configuration of Apache Geode/PCC using both spring.data.gemfire.* and spring.data.geode.* properties.

[jxblum]

This new feature would add support for both spring.data.gemfire.* as well as spring.data.geode.* properties.

Of course, some sort of precedence is required if duplicate, but equivalent properties are configured, for example:

spring.data.gemfire.cache.log.level=INFO
...

spring-data-geode.cache.log.level=WARN

For instance, should the log-level of the cache be WARN or INFO? 1 strategy could be that the last property definition wins. However, this can get quite confusing when the definitions are spread across multiple locations and property files, in addition to the use of Spring profiles.
