    Fix system cluster-show error updating string encoding

    When it was executed 'system cluster-show <uuid or name>'
    on a storage config, the error message "'str' object has no
    attribute 'decode'" showed. The error was caused because
    in upgrading from python 2 to 3 there were changes in the string
    encoding. In the latest version, there is no possibility to
    'decode' a string, and then it's necessary to remove it to
    ensure correct display of cluster information.

    Test Plan:
    Pass: Storage, cluster-show command return proper info.
    Pass: Standard, cluster-show command return proper info.
