[Refactor] Utskott as DB table

[afroborg]

This should probably have been done from the beginning as this will be a lot of work...
BUT - I think it's a necessary thing to do.

We should move away from the hard coded utskott enum in graphql and store utskott in the DB as well as relations to their respective posts.

This would be an improvement for many reasons:

1. No need to redeploy just to change a minor issue with naming etc.

I know this is not something we do often but it's still a pain to regenerate schemas etc. if an enum changes

2. We could add a description field to the utskott column, so that "utskottsordförande" can edit their own description on the site.
3. probably more reasons

My thinking is that it should have fields like:

• id - pk
• name - Ex. Informationsutskottet
• abbreviation - Ex. InfU
• shortDescription - A short description that summarizes the utskott
• description or articleLink - Either we store the entire description, or we link it to an article that describes the utskott in more detail.
• color? - Not sure about this, but could be a fun idea to let them decide their own utskott-color.

Agreed. But yes, a bit of a pain. Would also make it possible to change things about NollU when desireable

Will most certanly need a DataLoader, but that's probably easy to add
