NetApp driver should disallow very old controller OS versions

[Ben Swartzlander]

The NetApp drivers have been tested with various software versions, from 7.3 - 8.2. Versions 7.2 and older are unsupported, and the driver should detect the OS version at runtime and throw an error if it detects a version that is too old. This will reduce bugs and support issues related to people running unsupported versions.
