Add shared Makefile used by all components

[suokko]

A shared Makefile aims to remove duplicated image build and deployment
targets from each component. Avoiding duplicate Makefile targets makes
it easier to maintain a working deployment.

I created an example branch how to use the shared makefile in DDS service. I also pushed an annotated tag which makes git describe output more than just a commit hash for version.

I love it! I'm a big fan of DRY.

I have not tested this. I don't know whether our existing deploy process is working - that makes me less inclined to try a new one.

Please add a comment as to what's going on here.

This is based on @kiat-huang 's changes which managed to deploy to production. I don't know if my deployment code works because docker push returns Access denied.

I added some comments to the Makefile.

@kiat, let's get @suokko and all the knaves the access we'll need to deploy. Let me know if I can help test this. I'd hate to push a new deploy procedure without a demonstration that it works.

I create a personal cluster. My cluster isn't exact copy of production because terraform failed with a permission error. I have no idea how terraform can fail when it should be using service account with same privileges as I have.

I used Makefile to deploy dds (make deploy GCP_PROJECT=deal-test-project GKE_ZONE=europe-west4-a GKE_CLUSTER_NAME=bridge-cluster). After I manually exposes the deployment I managed to solve the example deal using curl. (My cluster doesn't have correct load balancer set up for automatically exposing application)

$ curl --header "Content-Type: application/json" --request POST --data '{"hands":{"S":["D3", "C6", "DT", "D8", "DJ", "D6", "CA", "C3", "S2", "C2", "C4", "S9", "S7"],"W":["DA", "S4", "HT", "C5", "D4", "D7", "S6", "S3", "DK", "CT", "D2", "SK","H8"],"N":["C7", "H6", "H7", "H9", "CJ", "SA", "S8", "SQ", "D5", "S5", "HK", "C8", "HA"],"E":["H2", "H5", "CQ", "D9", "H4", "ST", "HQ", "SJ", "HJ", "DQ", "H3", "C9", "CK"]}}' http://34.90.253.176/api/dds-table/
{"S": {"N": 8, "E": 5, "S": 7, "W": 5}, "H": {"N": 6, "E": 6, "S": 6, "W": 7}, "D": {"N": 7, "E": 6, "S": 7, "W": 6}, "C": {"N": 9, "E": 4, "S": 8, "W": 4}, "N": {"N": 7, "E": 6, "S": 6, "W": 6}}

To me it seems like deployment mostly works.
