    Remove the unsupported 'insecure_registry' for >=docker 3.0.0

    The argument of 'insecure_registry' for image push has been removed
    by this commit (in docker 3.0.0):
    https://github.com/docker/docker-py/commit/b180b8770a265e33099bd6da76c3e556a1028491

    Actually this argument was marked as deprecated and unfunctional
    before this removing.

    This commit is to remove this parameter at invoking the push() function
    when docker version >= 3.0.0.
