The api jar was added for xpack extensions. However, extensions have
been removed in favor of using SPI, and the individual xpack jars like
core and security are published to enable this. This commit removes the
api jar, and switches the transport client to use the core jar (which
the api jar was just a rename of).

* Add "client-api-objects" dependency for xpack plugin and transport-client
This adds another gradle project, "client-api-objects" which is intended to be a
common dependency so that the xpack plugin and transport-client can share the
same Request and Response objects.
Relates to elastic/x-pack-elasticsearch#2925
