Jira Link: DB-19492

Via yb_tablet_metadata view, it might be easy/helpful to expose information about tablet sizes for each replica.

(Much like Timur added support for it in the yb-master UI:

#29407 (comment)

in the "Raft Config/Replica" Info column).

(Customers would find it helpful to have this in a queryable manner rather than just in the UI).

Just like you show replica IP addresses as an array in yb_tablet_metadata view (see screenshot), we could add the active_ssts_size and wals_size as two additional array columns.
