> There are a number of issues and things which can be cleaned up related to
> PartitionNameWhitelistPreEventListener.
> * It's an event listener, but it really doesn't need to be given that the
> regex whitelist is configurable, it could just be a utility method.
> * It's not run when a partition is renamed, so partitions with invalid
> characters can be created in this way.
> * There's no easy way to check if a partition contains invalid characters
> before creating it and seeing if it fails.
> Most importantly, when a dynamic partition contains an invalid character, the
> directory for this partition is created, and the data is moved into it, but
> the partition fails to be created leaving an orphan directory.
