Merge #1913

1913: modify DISKS output to have only uri scheme and disk path r=abhilashshetty04 a=abhilashshetty04

We were returning bdev uri for disk field. We want to trim it to have only driver and path.

Before:

```
./target/debug/io-engine-client pool list

```   


After:

```
./target/debug/io-engine-client pool list
NAME     UUID                                 STATE  CAPACITY    USED USED% CLUSTER_SIZE PAGE_SIZE MD_PAGE_SIZE MD_PAGES MD_USED_PAGES MD_USED% DISKS                      DISK_CAPACITY ENCRYPTED
