Review comment:
I changed this so we were no longer parsing the long and just comparing
the string value. Let me know if you think this is the right approach.

> Implement Redis SELECT command
> ------------------------------
>
> Key: GEODE-8668
> URL: https://issues.apache.org/jira/browse/GEODE-8668
> Project: Geode
> Issue Type: Improvement
> Components: redis
> Reporter: Sarah Abbey
> Assignee: Sarah Abbey
> Priority: Major
> Labels: pull-request-available
>
> We are implementing SELECT because some Redis analysis tools (like Redis
> Insight) require the SELECT command in order to function properly. Since
> Geode Redis is similar to Redis in cluster mode in that currently it only
> supports database zero, we emulated the behavior of SELECT in cluster mode.
> Only database zero may be selected. All other valid DB indices (from
> -9223372036854775807 to 9223372036854775807) return the same error as Redis
> in Cluster mode: ERR SELECT is not allowed in cluster mode. Any DB indices
> that cannot be parsed as a long will return the error: ERR invalid DB index
