Add golangci-lint integration in CI

[rahulchheda]

FEATURE REQUEST

• In current CI, we have lint checks, but they seem not to detect all the linting issues, where as we can use golanglint-ci instead, which let use many linting plugins such as whitespaces, goimports, and many more, and these can be configured using config.
