Comment 5 for bug 1817688

Plan:
- master 001/004 are green and should vote; merge [0]
- confirm rocky/queens 001/004 turn green from [1][2]
- enable voting 001/004 in stable rocky/queens/pike
- stable will be voting again but pike jobs will be broken as it cannot use bluestore
- pike EOLs in five days [3] so a separate thread will cover disabling it
