* Revert "Revert "XdsClient: add unit test and fix watcher notification bugs (#30823)" (#30942)"
This reverts commit 6d2c4a8314.
* use GRPC_CUSTOM_JSONUTIL macro for JsonPrintOptions
This adds a unit test for XdsClient and fixes several watcher-notification bugs found in the process. Specifically:
- When an ADS stream fails or an xDS channel reports a connectivity failure, report an error only to the watchers for resources being subscribed to on that particular channel, not to watchers on other channels.
- Cache the error status for the channel, so that if a new watcher is started after the channel reports the error, we can immediately report that error to the new watcher.
- If a resource is NACKed and has not been previously cached, or does not exist, report that fact to any new watcher that may be started later.
- If a resource in an ADS response is unparseable but is wrapped in a `Resource` wrapper, we do know its name, so record the validation failure in the cache and report it to the watchers.

Previously this failed 1/1000 times with a 1s timeout, giving a
`Deadline Exceeded` error. I was able to reproduce the failure in
22/1000 times with a 500ms timeout. Changing it to a 2s timeout in this
PR, the failure did not reproduce in 5000 runs.

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
