Input validation needed for naming properties

[mtimm]

Here's an example of using the cli script where something obviously wrong happened and yet the script failed in a totally unexpected way. I alluded to it in the comments when I opened the issue. The behavior is now different on the exact same setup so it appears that the fabric I was using may have had an issue at the time that this occurred but the error that is returned is not what one would expect I think:

fabric(config)# tenant mtimm-acitoolkit
Executing create tenant command
fabric(config)# exit
fabric# switchto mtimm-acitoolkit
