added release automation

Highlights:
 - Uses GoReleaser for building and publishing releases to Github
 - Remove testing during the build process (will do done through Travis
 as presubmit)

-**First:** Download the latest `kubebuilder-release-<version>-<operating-system>-amd64.tar.gz` release. Extract it into /usr/local/ and update your PATH to include /usr/local/kubebuilder/bin.
+**First:** Download the latest `kubebuilder_<version>_<operating-system>_amd64.tar.gz` release. Extracting the archive will give `kubebuilder_<version>_<os>_amd64` directory. Move the extracted directory to /usr/local/kubebuilder and update your PATH to include /usr/local/kubebuilder/bin. Given below are the steps:
+
+```shell
+
+# download the release
+wget /path/to/kubebuilder_<version>_<operating-system>_amd64.tar.gz
+
+# extract the archive
+tar -zxvf kubebuilder_<version>_<operating-system>_amd64.tar.gz
+
+sudo mv kubebuilder_<version>_<operating-system>_amd64 /usr/local/kubebuilder
+
+#update your PATH to include /usr/local/kubebuilder/bin
+export PATH=$PATH:/usr/local/kubebuilder/bin
+
+```
