Store 'su' flag in jobs

[guewen]

"record.sudo().with_delay().foo()" generates a job that will be run
as sudo, keeping the current user, following the new implementation of
sudo/with_user of 13.0.

Closes #271

What is this travis failure on the branch? it passes on the pull request :/

The build displays on top, could be related:

/home/travis/.travis/job_stages: line 900: syntax error near unexpected token `fi'
/home/travis/.travis/job_stages: line 900: `fi'

Rebase maybe?

@sebalix
But this "Travis CI - Branch" job is bogus, generally we don't have both "Branch" and "Pull Request", but only "Pull Request".
IMO it should be ignored.

It would be cleaner to store the su flag in the jsonified recordset actually. I'll update my PR.

This PR has the approved label and has been created more than 5 days ago. It should therefore be ready to merge by a maintainer (or a PSC member if the concerned addon has no declared maintainer). 🤖

I'll reopen another implementation.

New implementation in #281, which brings a nice refactoring.
