Miscellaneous warning fixes
use com.spotify.logging, remove our duplicates
client: log version warning only once

Currently the cli will spam several warnings, one
for each request.
cli: hosts: fix docker version backwards compat

Helios pre-0.0.28 did not report docker version.
The hosts command thus NPE's on pre-0.0.28 helios
installations.
travis: only use two forks

Attempt to get fewer spurious travis failures.
use docker-client 2.3.1

docker-client 2.3.1 contains a fix where
ImageInfo fields would all be null due to
erroneous @JsonProperty annotations. This in turn
made the syslog redirection decorator NPE.
