Fixed! Thanks for your feedback! Do you mean it would be nice to have a 
test that would fail if `regionExists` always returns `true`, regardless of 
whether the region does or doesn't exist? I wrote a very simple test that does 
this and put it in `CreateRegionCommandTest`.

I don't see any tests that validate the behavior of this method.  I think 
we can simplify it to: 
```
private static boolean regionExists(InternalCache cache, String regionPath) 
{
if (regionPath == null || Region.SEPARATOR.equals(regionPath)) {
  return false;
}

ManagementService managementService = 
ManagementService.getExistingManagementService(cache);
DistributedSystemMXBean dsMBean = 
managementService.getDistributedSystemMXBean();

String[] allRegionPaths = dsMBean.listAllRegionPaths();
return Arrays.stream(allRegionPaths).anyMatch(regionPath::equals);
  }
```

But it would be nice to have a test that would fail with this 
implementation:
```
private static boolean regionExists(InternalCache cache, String regionPath) 
{
return true;
}
```

GEODE-3255: Refactor CreateAlterDestroyRegionCommands and tests

[View the JIRA ticket 
here.](https://issues.apache.org/jira/browse/GEODE-3255)

`CreateAlterDestroyRegionCommands` was a large class that contained 
multiple commands. Each command was refactored into a separate class, and the 
methods shared by the commands were refactored into a new and appropriately 
named class of their own. Tests related to `CreateAlterDestroyRegionCommands` 
were also refactored.
