Have you seen #970 ?

I am currently working on migrating all features that I built in my repo, while the project was not responsive.
When I finished the migration for the feature "priority field" I recognized your PR.
But I decieded to keep mine, because at the time when I was looking at your PR there were no tests included yet (see here)
Furthermore I think we should follow the pattern, that version checks should be done in code of provider package.

TBH: I don´t mind which PR we are going to merge ;)

@denniskniep @gim- Thanks for your work so far! I agree with @denniskniep to keep version checks in the provider package. On the other hand @gim- also adapted the data source which is missing in this PR. Can we somehow merge the two PRs?

@sschu @gim- I added priority attribute into the execution datasource

@gim- Are you fine with going for this PR instead of yours?
