afr: thin-arbiter read txn changes
If both data bricks are up, read subvol will be based on read_subvols.
If only one data brick is up:
- First qeury the data-brick that is up. If it blames the other brick,
allow the reads.
- If if doesn't, query the TA to obtain the source of truth.
TODO: See if in-memory state can be maintained for read txns (BZ 1624358).
updates: bz#1579788
