BUG-7033: Fix commit exception due to pipe-lining

The DistributedDataStoreRemotingIntegrationTest#testTransactionWithIsolatedLeader
has failed sporadically on commit with the "Store tree X and candidate
base Y differ" error due to an edge case bug with the pipe-lining. Basically
this occurs if tx 1 is pending completion of replication and tx 2 is progressed
to the COMMIT_PENDING state but the associated DataTreeCandidate has
ModificationType.UNMODIFIED. In that case we elide replication and proceed
immdiately to finishCommit which results in the error due to tx 2 committing
before tx 1. To fix it, I added a new FINISH_COMMIT_PENDING state and call
payloadReplicationComplete, which checks the head of the pendingFinishCommits
queue, when replication is elided..

Bug 7391: Fix out-of-order LeaderStateChange events

On leader transition, the current leader first sends out
LeaderTransitioning events to each follower to tell them the
current leader is being deposed. The followers send out a
LeaderStateChange event with a null leaderId which is picked
up by the ShardManager to delay subsequent transactions activity
to the shard until a new leader is elected. However it's possible
the LeaderStateChange message does not reach a follower until after
the leader transition occurs (eg due to dispatching delay in the
caller or the network). This results in a LeaderStateChange event
with a null leaderId being delivered after the LeaderStateChange
with the new leaderId. I wrote a unit test that reproduces it.

machine in ClientProxyHistory -- and failing to mark the successor
as sealed will wreck that.

Unfortunately an AbstractProxyTransaction does not forward all
of the state on seal(), but rather when the resulting commit
cohort initiates commit -- which means we have to perform three-way
synchronization between seal()/(can|direct)Commit/finishReconnect,
to ensure we flush state towards the backend exactly once.

To do that, we guard the methods involved with locking for split
them into fast/slow paths and add an explicit flushState() method
by which subclasses forward their current unsent state to their
successor. This solution is correct but a bit heavy-handed, so it
will be further optimized in a follow-up patch.

Bug 5419: Persist log entries asycnhronously

Modified RaftActor#persistData to persist the ReplicatedLogEntry
using akka's persistAsync method. This is similar to the persist method
except subsequent messages are delivered prior to persistence completion.
This avoids blocking the RaftActor so it can process AppendEntriesReply
and other messages while persistence is in progress.

In addition, AbstractLeader was modified to only count itself for consensus
when persistence is complete. This required communicating the persistence
complete state to the AbstractLeader. A transient persistencePending flag was
added to the ReplicatedLogImplEntry that is set by RaftActor#persistData
prior to the persist call and is cleared when the persist callback executes.
AbstractLeader checks the flag when counting consensus. It's possible that
the persistence complete event arrives after AppendEntriesReply messages
from replicated followers so a new message, CheckConsensusReached, is sent
by the RaftActor on persistence complete to check if consensus is reached.

BUG-5280: add AbstractClientConnection

Introduce a connection concept. This is a replacement for
the request queue, as it turns out we do need the concept
of a full connection (e.g. generational logic).

This comes from the need to sensibly switch behaviors
as the locality of the backend leader changes.

This patch implements two sets of strategies for dealing
with reconnect:

The first one assumes long-lived state and is used for
proxies dealing with histories. Here we make sure to
reinstantiate and replace them in a map, as we want
new transactions to follow the new semantic and we do not
want to tear histories down or follow inefficient paths.

The second one assumes short-lived state and is used for
proxies dealing with individual transactions. Transactions
are assumed to come and go rapidly and therefore we
do not replace the proxies in maps (as they will be
short-lived), but rather forwards operations to successors.

The first strategy has a higher access cost, but its state
is always fully uptodate when reconnect finishes, while
the second strategy favor access time, but operations end
up "trailing" and will be forwarded (and hence inefficient)
until the transaction completes.

Changes for akka 2.4.11

- Fixed compile error in MeteringBehavior as signature of onReceive now
  declares Throwable.

- Fixed intermittent failure in
  ShardManagerGetSnapshotReplyActorTest#testGetSnapshotTimeout. On failure,
  the actor would not get the ReceiveTimeout message from akka. However,
  oddly the test didn't fail if just testGetSnapshotTimeout was run - it
  would only fail if run with at least one of the other 2 tests. I tried
  creating a different ActorSystem for each test but that didn't fix it.
  I finally narrowed it down to creating the actors via the TestActorFactory
  although the exact reason is unknown. The tests don't really need to use
  the TestActorFactory so I remove its use.

- Fixed intermittent failure in
  ShardTransactionTest#testShardTransactionInactivity. This was the same issue
  as the ShardManagerGetSnapshotReplyActorTest, i.e. the actor would not get
  the ReceiveTimeout message when no other message was sent. I found the
  TestActorFactory was again the culprit. I narrowed it down to the
  verifyActorReady method which creates an ActorSelection and sends an
  Identify message. This was put in to work around messages intermittently
  going to dead letters shortly after actor creaton. It seems this code
  somehow may interfere with the ReceiveTimeout functionality. So to workaround
  this, I allowed the caller to elide the verifyActorReady call.
