Fetch "severity" from BZ

[voxik]

It seems that Bodhi now requires "severity" field for security updates (#2206):

$ fedpkg update 
Could not execute update: Could not generate update request: Missing update type, which is required to create update.
A copy of the filled in template is saved as bodhi.template.last

I don't understand why I should take a look at BZ, when Bodhi could fetch this information from BZ (although it might be a bit more difficult when single update addresses multiple CVEs).

Also, I wonder why this was not announced, why this is not supported in fedpkg and why security guys are probably not aware of this change since their template does not include the "severity" field
