Tempest test failed because backend driver can not handle security service with fake data is used

[zhaohua]

When set “$MULTITENANCY_ENABLED=True” to run tempest, the case "test_delete_ss_from_sn_used_by_share_server" will always faile.
I found it because the case use fake data in security service, and the backend driver can not handle this fake data.
I found another two cases(test_try_update_valid_keys_sh_server_exists, test_try_update_invalid_keys_sh_server_exists) also use the fake data. But the procedure of backend driver is wrap around "try...except". So the error of backend driver is ignored.
I think it's necessary to change the case "test_delete_ss_from_sn_used_by_share_server" to ignore the error of backend driver.

    Fix tempest case "test_delete_ss_from_sn_used_by_share_server"

    The case use fake data in security service, which may cause backend driver
    fail.
    Refer to the case "test_try_update_valid_keys_sh_server_exists", just ignore
    the error of the backend driver procedure.
