Fixes: #689, #690 Refactor container inspection code into a package of its own with some rudimentary tests. Use this package consistently in osd commands dealing with containers. Improvements for the next PRs: * implement API to fetch info about container by ID (to avoid fetching full list) * handle and display errors on client side, not to the log of the server * more tests, including k8s containers (how can we do that?)
