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).
