Add Dockerfile for CLI

[ryanwalls]

Helps with #729. Would need someone to automate running it in your builds and pushing to docker hub.

@vancexu can you take a look at this PR.

Thanks for this contribution @ryanwalls ! I am trying to understand how you are going to use this docker image before merge it.

I create the docker image using your Dockerfile and then run it withdocker run image-id, return error exec user process caused "exec format error". (same error with args like docker run image-id --do test d desc), do you have clue how to address this?

@vancexu Hummm. Try running my built image directly and let me know if you see that error.

docker run --rm ryanwalls/cadence-cli:0.5.3

I'm on this Docker version:

Client:

 Go version:   go1.9.5
 Git commit:   33f00ce

As far as how I plan to use it, I'm just going to use this container to run one-off CLI commands as needed. e.g.

docker run --rm -it ryanwalls/cadence-cli:0.5.3 --do qa --ad cadence.default:7933 wf listall

Or if I'm connecting to my kubernetes cluster:

kubectl run tmp-shell --rm -i --tty --restart=Never --image=ryanwalls/cadence-cli:0.5.3 --command -- /bin/bash -c "./cadence --do qa --ad cadence.default:7933 wf listall"

[vancexu]

@ryanwalls use your image works as expected. How did you build the image?
I was using docker build -f Dockerfile-cli -t vancexu/cadence-cli:0.5.3 . which return above mentioneds error when run.

[ryanwalls]

@vancexu The image was built automatically with Docker hub.

[ryanwalls]

@vancexu Were you able to figure out why your local Docker was having trouble? Like I mentioned, it works on my machine and on Docker Hub (where the image was built.)

[vancexu]

@ryanwalls The issue disappeared after I update my docker to latest. Looks good and merged. I will change it a little bit and move it to docker folder later. Thanks again for contribution!

[vancexu]

Update a little bit #793
