Matthew L Daniel b0a85f6ca3 Guard against improper auto_expand_replica values
Previously if the user provided a non-conforming string, it would blow up with
`java.lang.StringIndexOutOfBoundsException: String index out of range: -1`
which is not a *helpful* error message.

Also updated the documentation to make the possible setting values more clear.
