Automatic tagging of builds in Docker Hub

[haxorof]

When a release of prometheus-sql is done no tag is created for that in Docker Hub. Basically if non-compatible changes are introduced then it will not be possible to revert back to for example version 1.1.0.

As written in this post below it is possible to easily get versions to the builds in Docker Hub as soon as you tag in Github: https://stackoverflow.com/a/44796846

@bruth: Possible to fix?

Configuration basically looks like this:

Type	Name	Dockerfile Location	Docker Tag Name
Branch	master	/	latest
Tag	/^([0-9]+).([0-9]+).([0-9]+)$/	/	{\1}
Tag	/^([0-9]+).([0-9]+).([0-9]+)$/	/	{\1}.{\2}
Tag	/^([0-9]+).([0-9]+).([0-9]+)$/	/	{\1}.{\2}.{\3}

I updated the Docker hub build settings.

Great! Then lets see if some tagged build happens the next time a new tag is pushed to Github :octocat:.
