Allow for template on voting comment

[potiuk]

When we are voting, we should generally state what we have done as testing.

Currently when you press +1, the comment is empty, and since it is a button, this will lead to mostly empty comments with +1.

It would be great if the comment could be prefilled with something like (see markdown version) - coming from a per-project template:

• Checked SVN
• Checked in Docker
• Checked reproducible package builds
• Checked licenses
• Checked signatures

Ideally you should not be able to press +1 if any of the [ ] is not turned into [x]

Bonus point is that markdown could be converted into actual check-marks - like Github does.

This checklist is somehow derived from the PMC's checklist. If we take this approach to the ballot then the list of required checks is from a selection of required and PMC selected.

Ideally yes. If we can make it somehow configurable once for both cases - that would be great.
