[RFE] Volume details (i.e. brick details) should identify bricks that are arbiter

[julienlim]

As a Gluster admin, I want to be able to know which bricks are arbiter bricks. Note: Just looking at volume type does not tell me if a volume is a distributed-replicat using the arbiter feature or not.

# gluster volume info

Volume Name: testvol
Type: Distributed-Replicate
Volume ID: ae6c4162-38c2-4368-ae5d-6bad141a4119

Bricks:

Brick2: server2:/bricks/brick
Brick3: server3:/bricks/brick (arbiter)
Brick4: server4:/bricks/brick
Brick5: server5:/bricks/brick
Brick6: server6:/bricks/brick (arbiter)

I proposed that we show arbiter in Brick Details and also show device UUID in the Brick Details.

Regarding UUID, due to hot swappable disks being commonly used, it would be good to show the device UUID as this is needed for Day 2 and Day 3 operations, e.g. disk/brick replacement.

For the Brick Details views for the Host and Volume, I suggest we do the following:

• Add new column to indicate if brick is an arbiter or not
• Remove Port column
• Add new column for UUID; Note: This is similar to information one gets from running the ls -l /dev/disk/by-uuid command.
• Add filter option for Arbiter (Filter by Arbiter Brick, Data Arbiter), Disk Device UUID

The following is a brick details for Volume mockup:

@julienlim , this new column is visible only for arbiter volumes?
