• [ ] Remove JobQueue SLURM driver
• [ ] Remove JobQueue LSF driver
• [x] #7912
• [ ] #7985

• [x] #8200

NB! Be aware that --disable-scheduler will stop working once we remove the old code, which implies that even-though users have specified LSF as queue, when running it as test_run with --disable-scheduler will want to use JobQueue LOCAL driver.

Blocked until the feature freeze in komodo August release!
