Add a NetBackup client image to the SRT

The options for adding a NetBackup client image to the shared resource tree are as follows:

An SRT must contain a NetBackup client image that is the same version as the system(s) to be protected.

If the SRT already contains a NetBackup client image, it is replaced.

An SRT without a NetBackup client is in the Defined state; Ready state indicates a NetBackup client image is installed.
