GEODE-8996: Fixed rebalance gfsh and REST API in mixed version mode (… (#6257)
* GEODE-8996: Fixed rebalance gfsh and REST API in mixed version mode (#6080)
* Moved new child RebalanceFunction and CacheRealizationFunction to pre
1.12.0 locations.
* While talking to pre-1.12.0 servers, the locators send the function from
the old package.
* While talking to 1.12.0 server, the new package function is used.
* For RebalanceFunction and CacheRealizationFunction the serialVersionUID is
set to the one created by 1.11.0 for old package location and serialVersionUID
created by 1.12.0 for the latter.
* Update GfshCompatibilityTest.java
(cherry picked from commit 3faf283c038880755a7356fe570a4f92a46826cd)
> Rebalance GFSH commands and restore redundancy commands were not backward

> Project: Geode
> Issue Type: Bug
> Components: gfsh, rest (admin)
> Reporter: Nabarun Nag
> Assignee: Nabarun Nag
> Priority: Major
> Labels: blocks-1.14.0, pull-request-available
> Fix For: 1.13.2, 1.14.0, 1.15.0

> Issue:
> * Rebalance command when executed with 1.12.0+ locator and older servers,
> the command failed
> * This was because the Rebalance function moved to a new package
> * Similar problem with REST calls because of moving CacheRealizationFunction
> to a new package
> * There was another problem where Serializable classes with UIDs were
> changed in couple of releases
> * The variation of the UIDs caused deserialization issues when REST commands
> were executed from new locators and old servers.
