Add partition detection to fix osd initialization failure
Add partition detection to fix osd initialization failure

The changes in the following commit did not completely solve the
problem of osd initialization failure:
https://review.opendev.org/652612

In order to solve this problem, the partprobe command consistent with
ceph-disk is added, and then a loop is added to detect the partition,
which is acquired every 1s. When the partition appears, the osd
initialization is continued.
