As the-end user of NDS Labs, it would be nice to be able to edit a spec to my personal catalog. This would allow me to, for example, change to different Docker tag for a particular spec to test a new version of the software.

This functionality is provided by NDS-357 (import spec) + NDS-360 (delete spec), but this could potentially be much more user-friendly.

This form should simply be a verbose listing of all fields on a spec:

• Key (should this be editable?)
• Label
• Access? Internal / External / None
• Display? Stack / Standalone / None / (DevStack?)
• Dependencies
• Configuration Options
• Volumes
• Ports
• etc...

This story is complete when the user can access a form allowing them to easily author a spec and add it to their personal catalog from the NDS Labs UI.

Aside: Are there security concerns with this?
