    Fix name pattern for DockerApp

    Currently name pattern for DockerApp allows to use underlines, dots and
    doesn't limit name length (at least that's described in field description).
    This occurs validation error with some regexp. Kubernetes docs [1] indicates,
    that container name should be DNS_LABEL, which described in [2]. Also,
    kubernetes code [3] contains regexp and length limit for DNS_LABEL
    pattern.
