    Copy package_checksums to <software_version>_packages_list.txt

    The prestaging operation on the system controller requires the list
    of packages and their checksums in a file named
    "<software_version>_packages_list.txt", where <software_version> is
    the version of the system controller (i.e. the new version which the
    subclouds are being upgraded to).

    Currently, the file is stored as package_checksums. This causes
    the prestaging operation to fail.

    This fix ensures that the list of packages and checksums is stored
    correctly as <software_version>_packages_list.txt at
    /usr/local/share/pkg-list when a subcloud is installed. The file
    will then be available for future prestaging operations with the
    right name.

    Test Plan:

    PASS: Verify that prestaging of packages for upgrade is successfully
          executed.

    PASS: Verify that the file is correctly stored as
          <software_version>_packages_list.txt at
          /usr/local/share/pkg-list when adding a subcloud.

    PASS: Verify that package_checksums is copied to
          /usr/local/share/pkg-list as <software_version>_packages_list.txt
          when upgrading the system controller to a higher version.

    PASS: Verify that package_checksums is copied to
          /usr/local/share/pkg-list as <software_version>_packages_list.txt
          when installing a controller over pxeboot

    PASS: Verify that package_checksums is copied to
          /usr/local/share/pkg-list as <software_version>_packages_list.txt
          when adding a subcloud from the system controller (using dcmanager
          add)

    PASS: Verify that package_checksums is copied to
          /usr/local/share/pkg-list as <software_version>_packages_list.txt
          when installing a system controller in virtualbox from
          bootimage.iso.
