Add support for category header

[campb303]

Per a conversation w/ @sundeep : Add support for parsing and updating a new custom header to track an item's category if/when said header is added to the queue-cli.

• I have searched the issues of this repository and believe that this is not a duplicate.

Problem

The assignment and priority fields for items are interchangeably used to track a class/category of item e.g. emuffley and 0-FYI are both common assignments but only the former is an assignment to a person. This makes it difficult to programmatically address the assignment field.

Similarly, people use the priority field is various arbitrary ways like numeric ranking (1, 2, 3...) or relative adjectives (low, medium, high) but in recent month priority has also been used to track issues related to COVID.

The ambiguous use of these fields makes it difficult to programmatically interact with them due to the variety of content that can appear (usernames, groupings, numbers) and the multitude of delimiters that can be used (comma ,, comma plus space , , forward slash /, backward slash \, space etc.)

Proposal

@sundeep will start the conversation about adding this header to the queue-cli scripts. If/when this happens, we should know the name and expected formatting of this header.

Sundeep talked w/ Curtis and this isn't something that Curtis will implement but this can be added by webqueue2 independently. Thought should be given to how to backport this to queue-cli though.

This will not be completed by the current team. It requires write support in the API.
