Disregard healing disks in crawling (#10349)

Browse Source 
When crawling never use a disk we know is healing.

Most of the change involves keeping track of the original endpoint on xlStorage
and this also fixes DiskInfo.Endpoint never being populated.

Heal master will print `data-crawl: Disk "http://localhost:9001/data/mindev/data2/xl1" is 
Healing, skipping` once on a cycle (no more often than every 5m).
