VOL-546 Add support for proxy servers in build

- Propagate proxy environment variables into docker builds
- Generate mvn settings.xml based on proxy env vars and allow custom xml
- Update to latest docker installation within go-lang docker image (to avoid apt-key proxy issue)
- Allow additional parameters with DOCKER_BUILD_EXTRA_ARGS, for example --no-cache, --pull
- Also fixes 'overriding recipe for target' for voltha target

Change-Id: Ifa545a0262ecfe434ad230ddab4f61935c7244e0
(cherry picked from commit e0c9acbbd529b38da0adacdb6701cb0e37553119)
