[Feature][ibm_zos_data_set][L2] Support disposition share (DISP=SHR)

[ddimatos]

FEATURE

Module ibm_zos_data_set could benefit from supporting the disposition share (DISP=SHR) so that a member can be updated when a PDS/E has been open but a started task and will not be released. This would allow the module to force a change.

This will require that ZOAU support DISP=SHR in ZOAU utility mrm.

An example of this is a member being deleted using zos_data_set module:

    - name: "Delete the member(s) from PDS(s)"
      zos_data_set:
        name: "HLQ.MLQ.LLQ(APP1)"
        state: absent
        type: MEMBER

Results in:

"DatasetMemberDeleteError('An error occurred during deletion of data set member\"HLQ.MLQ.LLQ(APP1)\". RC=1')", "names": ["HLQ.MLQ.LLQ(APP1)"]}

Source of interest in the module:

        Raises:
            DatasetMemberDeleteError: When data set member deletion fails.
        """
        rc = datasets.delete_members(name)
        if rc > 0:
            raise DatasetMemberDeleteError(name, rc)
