    Exclude http store if --all-stores specified for import/copy operation

    If operator has configured read-only 'http' store in multiple stores and while
    importing or copying existing image in multiple stores if user has specified
    --all-stores true then depending on `allow-failure`; if it is True then image
    is imported/copied to other stores than http or if it is false then image can
    not be imported/copied to other stores as well. Aslo, new image property
    `os_glance_failed_imports` shows `http` as failed store.

    Excluded `http` store from the list of stores for import/copying workflow
    if user specifies --all-stores as True.
