priority:
- go back to starting failover timer upon CONNECTING, but only if seen
READY or IDLE more recently than TRANSIENT_FAILURE
ring_hash:
- don't flap back and forth between IDLE and CONNECTING; once we go
CONNECTING, we stay there until either TF or READY
- after the first subchannel goes TF, we proactively start another
subchannel connecting, just like we do after a second subchannel
reports TF, to ensure that we don't stay in CONNECTING indefinitely if
we aren't getting any new picks
- always return ring hash's picker, regardless of connectivity state
- update the subchannel connectivity state seen by the picker upon
subchannel list creation
- start proactive subchannel connection attempt upon subchannel list
creation if needed
* ring_hash: fix connectivity state seen by aggregation and picker

* refactor connection injector QueuedAttempt code
* add test showing that ring_hash will continue connecting without picks
* clang-format
* don't actually need seen_failure_since_ready_ anymore
* fix TSAN problem
