deploy test-asset.yml build artifacts with teraslice-cli

Asset PRs create build artifacts on every push. It would be great if the teraslice-cli could deploy these artifacts by just giving the commit sha of the artifact you want to use.

Currently we can grab an asset from the repo based off of the release:
teraslice-cli assets deploy localhost terascope/[email protected]

I was thinking we can replace the release tag with the short sha or full sha:
teraslice-cli assets deploy localhost terascope/elasticsearch-assets@3b0f8d5
teraslice-cli assets deploy localhost terascope/elasticsearch-assets@3b0f8d52194ffa30a4ef91b134104d6687c61c22
