Description of problem:
Running on an upgrade from CS8 to CS9, and I'm running into an issue with my VDO disk import. It appears that the script `lvm_import_vdo` relies on the `vdo` script but it is was deprecated and removed.

Version-Release number of selected component (if applicable):
2.03.21-1

How reproducible:
Run lvm_import_vdo and observe error.

Steps to Reproduce:
1. `# lvm_import_vdo --dry-run <known-vdo-volume-created-in-CS8>`

Actual results:

[root@core ~]# lvm_import_vdo --dry-run /dev/md1
lvm_import_vdo: Checked whether device /dev/md1 is already LV (0).
lvm_import_vdo: Getting YAML VDO configuration.
/sbin/lvm_import_vdo: line 278: vdo: command not found

Expected results:

Successful import.
