Bug 8885: Fix DistributedShardedDOMDataTree initialization

DistributedShardedDOMDataTree initialization expects the prefix
configuration shard to be present and ready with leader however
the latter isn't the case when the static module-shards is
bootstrapped without the local member so it can be dynamically
joined into an existing cluster. So I modified the ConfigShardLookupTask
to elide the ConfigShardReadinessTask.

Once past that, creation of the prefix-based default shard is attempted
as there isn't a local module-based shard however this fails b/c the
local prefix configuration shard is not connected to a leader. To alleviate
this I just commented out the code to create the shard. Since the default
shard configuration is present in the out-of-box modules.conf and is
expected to be present, we can assume at this point that the local member
isn't in the replica list with the intention of dynamically joining it to
an existing cluster, at which time the shard will be created.

These changes at least fix the regression with the boostrapping scenario.
We can revisit this iniialization later w.r.t. prefix-based shards.

so a separate executor for callbacks is used now.

The delay would not be that critical, but the problem is the timing
between a scheduled execution which exceeds scheduling gaps. These
seem to hold up normally-submitted tasks, leading to futures never
completing.

Therefore we use two Executors and synchronize state modification
call sites. Hence the two tasks (throttled producer) and future
completions can run concurrently (aside from state synchronization).

BUG-8403: fix DONE state propagation

The DONE state detection logic in replayMessages() was flawed, as
we checked the current state, which is guaranteed to be SuccessorState.

We should be checking the previous state, available from the successor
state. As it turns out we can do this very cleanly by setting the flag
when the successor state gets the previous state assigned.

This also has better performance, as we do not touch the volatile
field multiple times.

BUG-8494: fix throttling during reconnect

ReconnectForwarder is called from differing code-paths: the one is
during replay when we are dealing with late requests (those which have
been waiting while we replaying), the other is subsequent user requests.

The first one should not be waiting on the queue, as the requests have
already entered it, hence have payed the cost of entry. The latter needs
to pay for entering the queue, as otherwise we do not exert backpressure.

This patch differentiates the two code paths, so they behave as they
should. Also add more debug information in timer paths.

BUG-8403: propagate DONE state to successor

We need correct accounting for DONE non-standalone local transactions,
