Subject: [PATCH] Build: Add api jar and client jar for xpack

This adds back (again) building a transport client plugin jar for
x-pack, and also adds producing an "api" jar which extension authors can
build against. For now, both these jars are exactly the same, but
eventually they could differ, and be reduced to less than the real
x-pack jar.

see elastic/stackelastic/elasticsearch#7
