fedpkg update can be used two ways: either by using $EDITOR to fill out an update template, or by specifying values via --command-line-args.

However, there is no support for a --severity argument, which is required for security updates. This, in turn, means that security updates can only be submitted using the "edit the template" workflow.

Observed behaviour
Trying to submit a security update by using:

fedpkg update --type security --severity medium --notes 'Fix for CVE-XYZ-ABC' --bugs 999999999

Results in an error:

fedpkg: error: unrecognized arguments: --severity medium

Expected behaviour
The --severity XXX option is supported and recognized, and the security update is submitted successfully.
