MetadataRequest => [topics]
Stays the same as version 0 however behavior changes. 
In version 0 there was no way to request no topics, and and empty list signified all topics.
In version 1 a A null topics list (size -1 on the wire) will indicate that a user wants no ALL topic metadata. Compared to an empty list (size 0) which indicates metadata for all NO topics should be returned.
