GEODE-5884: Added new command and restored pre 1.8 region function behavior
(#2829)
* Due to the refactor that caused us to lose wrapping of exceptions,
the fix to GEODE-5884 cannot be applied to GEODE 1.0-1.7 clients
* Adding new command class will allow clients to identify which function class
it is expecting to execute and what behavior to expect
> Executing a function with non HA should return any available partial results

> Key: GEODE-5884
> URL: https://issues.apache.org/jira/browse/GEODE-5884
> Project: Geode
> Issue Type: Bug
> Components: functions
> Affects Versions: 1.0.0-incubating
> Reporter: Jason Huynh
> Assignee: Jason Huynh
> Priority: Major
> Labels: pull-request-available
> Time Spent: 3h
> Remaining Estimate: 0h
>
> When a function is executed without single hop, it is sent to a
> "coordinating" node. This node then creates tasks that are executed on other
> remote nodes and itself. If any of the remote nodes or the local node gets
> an exception, it will accumulate the exception and any results it has
> currently received. It then completes and sends those results back to the
> client.
> There is a flag to waitOnException. We should set this to true if the
> function is non HA. This will have the coordinating node wait for all
> results before sending back to the client. The work is going to get executed
> on the remote nodes anyways, so why not wait for the results?
> This will mirror a single-hop execution where a single node may fail. If it
> does, the client still receives results from the other nodes.
