Newly added auto-fix feature for goimports into golangci-lint 1.15.0.
So we can use this for fixing go format in our tasks,
i.e. pre-commit, check:backend and fix:backend.

Also, added config file for golangci-lint as `.golangci.yml`.

Standalone goimports installation was removed in favor of this.

"check:backend" task always return success even if linters reported errors now.
And golangci-lint does not work properly outside `${GOPATH}`.

Removed `--issue-exit-code=0` option for `golangci-lint` and change directory
into `${GOPAHT}/src/github.com/kubernetes/dashboard` before run `golangci-lint`
on Travis CI.

Also, added `enable=goimports` option for `golangci-lint` and
applied "goimports -w src/app/backend".
