  - k8s: Resolve Docker response formatting issue

    Checker collects information on cluster by Docker queries:

    $ docker ps ARGS...      # Casablanca
    $ docker inspect ARGS... # Dublin

    Arrays of values are then filtered from those. They include:

    * opening bracket ('['),
    * closing bracket (']'),
    * new line.

    Additional characters affect check results if last flag (including
    "]\n") requires specific value.
