openshift java client: remove various API elements (show ports etc.)

I am planning to break 1.0 compatibility for some REST APIs which I think are not in use. Please correct me if this you are aware of some client which uses these APIs.

/rest/estimates/*
	Estimates API was created for use by UI to calculate estimated number of gears used for a given app descriptor.

/rest/domains/#{dom_id}/applications/#{app_name}/events # show-port, expose-port, conceal-port
	*port APIs were created for testing Rob's code. Not aware of anyone using them now.

/rest/domains/#{dom_id}/applications/#{app_name}/gears
	gears API was in use by UI before gear-groups were exposed to get a list of gears in the application. Not aware of anyone using them now.
