docs: export Subclients embedded struct (#126)

* docs: export Subclients embedded struct

embedding a private struct creates the confusing effect of exporting the public fields of the sub-struct without having them show in documentation.

This has some discussion at the language / godoc level: golang/go#6600

This commit exports the subclients field of goobs.Client so the available fields show in documentation.
