HDS HNAS driver fails when creating snapshots

[Tiago Pasqualini da Silva]

HDS HNAS driver fails when tracking HNAS tree-clone-job status. Because of that, it sometimes keeps snapshot status on "Creating" until it timeouts and changes this status to "Error".

    Fix HDS HNAS snapshot creation tracking

    HDS HNAS driver fails when tracking HNAS tree-clone-job status,
    thus it incorrectly triggers snapshot creation timeout. This occurs
    because the JobStatus class cannot successfully parse the HNAS
    tree-clone-job status command output. This patch fixes these class
    issues.
