Description of the PR

fixes:#3156 (closed)

Jersey2 client is relying on jersey-client dependency of 2.27 version. After jersey-client 2.26 version, hk2 which is a hard dependency of jersey-client was removed. They created an SPI as a facade for the dependency injection provider, in the form of the InjectionManager and InjectionManagerFactory. So for Jersey to run, we need to have an implementation of the InjectionManagerFactory. More details are available here(https://stackoverflow.com/a/51217530/3044493).

For supportJava6 option, we are using older version of jersey-client which has hk2 as hard dependency and so we need not add jersey-hk2 while generating library with that option.
