[WIP] remove unnecessary pkgs in Dockerfile

[weiguoz]

fix #40

[typhoonzero]

We should update sqlflow to not use this image directly first before removing these deps: https://github.com/sql-machine-learning/sqlflow/blob/develop/.travis.yml#L33

Line 146 in 7240393

COPY dataset/create_model_db.sql /dataset/create_model_db.sql

Should also be reverted.

Discussed with @weiguoz I'll try to put hive server container at background in CI, so that we can remove deps here.

Duplicated with #42. Since this PR is titled with WIP, I choose to close this one.
