tests/bcachefs: add three tests to replication.ktest

test_device_repeated_add_remove(){
    Test rapidly adding and removing the same device.
    Caught bugs:
      -  found a race condition that leads to a kernel BUG in btree_key_cache.

test_add_label(){
    Test setting device label when adding
    Caught bugs:
      - label was not set correctly; set to dev-0 label instead of new one.

test_add_compound_label(){
    Test adding a device with a compond label, a '.' separated "path"
    (e.g. ssd.sata)
    Caught bugs:
      - filesystem crashed with message "Invalid superblock section disk_groups".
