Description

cross test jobs on Travis-CI are frequently hitting 50 min limit.
For now, reducing docker build time by several minutes should fix it.

Dockerfile changes:

• buildpack-deps base image for fewer apt packages
  https://hub.docker.com/_/buildpack-deps

• fewer apt-get packages
  It would cause problem for retrying. in that case we can split them again

.travis.yml changes:

• remove "docker pull" because cache can no longer be reused because of docker change
