Modify imports ordering with goimport

[mbeacom]

With goimport, all of the imports will be restructured to adhere to golang import package precedence and ordering by https://godoc.org/golang.org/x/tools/cmd/goimports to make it a little cleaner

@winlinvip @mbeacom I found the easy solution. Just run goimports -w . on the root of the repo. It will format all the codes and write the changes to the file.

@winlinvip goimports -w . against the project root will replicate the changes proposed in #60 Thanks @Akagi201
