Add Bulk Edit to ConfigContext

[bdlamprecht]

Environment

• Python version: 3.6
• NetBox version: 2.4.5

Proposed Functionality

Similar to the way that you can bulk edit devices, device-types, ip-addresses, prefixes and others, I'd like to see if the same functionality can be added to config-contexts.

The only values that immediately make sense to enable bulk editing are weight and active. I could see the potential to include assignments as well, but I have a feeling that could be opening a "can of worms" that we don't want to deal with.

Use Case

As an example, this is a screenshot of my config-contexts in the WebUI:

Suppose I want to change the weight on all of them due to a change in structure, I would have to manually edit each one. If a bulk edit were enabled, this could be done much easier.

As another example, suppose I'm trying to resolve an issue with the way config-contexts are being rendered on a device, being able to bulk edit them to temporarily change the active status would be extremely helpful.

Database Changes

I don't believe there should be any as config-contexts are a primary model.

External Dependencies

None.
