By checking https://github.com/moby/moby/blob/master/CHANGELOG.md, I got the 
following info:
1. `--dns-opt` was introduced to `docker run` in Docker 1.9.0, see 
https://github.com/moby/moby/pull/16031.
2. `--dns` can be used with `HOST` network in Docker 1.12.0, see 
https://github.com/moby/moby/pull/22408.
3. `--dns-option` was introduced to `docker run` in Docker 1.13.0 and 
`--dns-opt` was hidden (but it still can be used), see 
https://github.com/moby/moby/pull/28186.

I will do Docker version check based on the above info in 
https://reviews.apache.org/r/60558/.
