Enable markdown in custom field description fields and custom validator error messages

[decoupca]

NetBox version

v3.3.6

Feature type

New functionality

Proposed functionality

Enable markdown syntax on custom field descriptions and error messages in custom validators. Not all syntax options need to be supported; at least boldface, italics, and links.

Use case

The ability to link to outside content (e.g. documentation) in either descriptions or error messages would be helpful. Formatting options like boldface and italics can make error messages easier to understand.

Database changes

Possibly expand the maximum length of custom field description fields, as markdown syntax may significantly increase the value stored.

External dependencies

None
