Update dockerLabels in the Task Definition from Docker Labels.

[haber-he]

We added below labels during the docker images build, but the docker Labels are ignored by ECS when I deploy a task definition. --label "git.commit=${GIT_COMMIT}"
--label "git.branch=${GIT_BRANCH}"
--label "built.time=$(date +'%Y-%m-%d %T')"
--label "built.by=$(whoami)"
--label "built.url=${BUILD_URL}" \

so it's will be great if can update the dockerLabels in the Task Definition from Docker Labels during the Task Definition create.
