This reverts commit 4e8bd619dd.

The original doc is correct. The 5GB journal is create in ceph-osd
bootstrap script in kolla code base[0]. And there is no script to handle
KOLLA_CEPH_OSD_BOOTSTRAP_D label too.

Using an external journal drive
-------------------------------
Create a journal partition of 5 GByte and a data partition with the remaining
storage capacity on the same tagged drive.
::
parted /dev/sdb -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_J 0 5GB
parted /dev/sdb -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_D 5GB 100%
The steps documented above created a journal partition of 5 GByte
and a data partition with the remaining storage capacity on the same tagged
drive.
It is a common practice to place the journal of an OSD on a separate
journal drive. This section documents how to use an external journal drive.
