[FLINK-5559] let KvStateRequestSerializer#deserializeKeyAndNamespace()
throw a proper IOException
This adds the hint that a deserialisation failure probably results from a
`"mismatch in the key/namespace serializers used by the KvState instance and
this access"` to all thrown exceptions and throws proper `IOException`
instances instead of `IllegalArgumentException`.
The new unit tests require #3171 to be accepted first on which this PR is
also based.
