Review Comment:
There's a Doris startup stage where `SHOW BACKENDS;` outputs rows while its
available disk capacity is zero.
```
*************************** 1. row ***************************
BackendId: 10004
Host: 127.0.0.1
Alive: true
(...)
TabletNum: 0
DataUsedCapacity: 0.000
TrashUsedCapcacity: 0.000
AvailCapacity: 1.000 B
TotalCapacity: 0.000
(...)
```
Though backend declares itself as "alive", any DDL operations will fail due
to a no-disk-available error. Explicitly waiting for disk to initialize fixes
this problem.
