Add few warning compiler options to error (#1181)

* add conversion, unused-but-set-variable, and return-type warnings to error
* add shadow variables to error and their fixes for code compilation
* apply the same flags to controller interface package
* apply the same flags and their fixes to hardware_interface package
* apply the same compiler options to the rest of the packages

(cherry picked from commit 65353ff)
