look at directory spec.d/tomcat

todo

• Implement this with ruby docker API

if NSENTER_PID empty
# check docker_enter
NSENTER_PID=`docker inspect -f '{{ .State.Pid }}' #{DOCKER_CID}`

• more working examples
• add testcase
• add an implementation that use docker 1.3 docker exec
• check with docker container
• look add package check openjdk-8-jre-headless:amd64 failure
