32 - docker tag management

[ozbillwang]

• docker tag management with updated build number.
• remove tag 1.0.0, which is replaced with 1.0.<build_number>

the build error is not because of my codes. It is something wrong in drone pipeline, that doesn't support build from its fork repositories.

The approach we are taking with other repositories is we are updating latest on pushes to master, and we are only creating semver docker tags for tag events, like this:

  publish:
    image: plugins/docker
    secrets: [ docker_username, docker_password ]
    tag: [ latest ]
    when:
      branch: master
      event: push

  release_server_alpine:
    image: plugins/docker
    secrets: [ docker_username, docker_password ]
    tag: [ 1, 1.0, 1.0.0 ]
    when:
      event: tag

So while I appreciate the PR, we would instead adopt the above approach. @tboerger this is what we are doing for drone core. Thoughts on adopting this approach for plugins? If yes, I would suggest we first implement https://github.com/drone-plugins/drone-docker/issues/150, which should help streamline everything.

@bradrydzewski totally makes sense!
