CI fails according to network issues of git repo golint, see below:

RUN go get -u github.com/golang/lint/golint
 ---> Running in 15dec7a3a67a
# cd .; git clone https://go.googlesource.com/lint /go/src/golang.org/x/lint
Cloning into '/go/src/golang.org/x/lint'...
fatal: remote error: Git repository not found
package golang.org/x/lint: exit status 128
The command '/bin/sh -c go get -u github.com/golang/lint/golint' returned a non-zero code: 1
make: *** [cri-test] Error 1

Just record this.

Actually I have already considering to use a base image which includes all essential tools, rather than dynamically building one with dockerfile.

The golint issue is fixed in pr #1193.
