'--known-hosts-url' option but cannot be disabled
Reverts the previous commit and simplifies the semantics of setting
--ha-public-url and --ha-brokers-url. There is no longer any over-riding or
implicit updating of values. That means you must set --ha-public-url as well as
--ha-brokers-url, it will not be defaulted. Likewise if you *dont* set
ha-public-url, it will remain empty, which is the use case in this bug.
The defaulting was adding complexity without adding much value.

This commit provides better control over loading the HA module. In particular it
is not loaded if no ha options are set. This will prevent clashes with the old
cluster plugin in configurations where the HA module is not explicitly used.
HA documentation has been updated to state that HA and old cluster cannot be used
together.

initialized
A HA backup broker in a cluster rejects client connections. This was previously
done in a ConnectionObserver registered during Plugin::initialize. However that
left a window before the observer was registered when clients could
connect. This showed up as a sporadic failure of the failover test. This patch
moves the creation of the observer to Plugin::earlyInitialize, which is
guaranteed to be called before the broker starts listening for clients.

After a failure, the newly-promoted primary broker guards messages for each of
the backups that were connected at the time of the failure. It waits for them to
reconnect to the new primary before becoming active.
This patch introduces a time-out so that if an expected backup fails to
fail-over within the time limit, the primary will cancel the guards for that
backup and carry on.

QueueGuard: implements QueueObserver to delay completion of new messages.
ReplicatingSubscription: Implements subscription, sends messages & events to backup.
These were previously combined as one. QueueGuard is now separated out
so that it can be created before the ReplicatingSubscription, in
anticipation of an expected backup connecting. This is needed for 2 reasons:
- new queues must be guarded until they are backuped up.
- after a failover, all queues must be guarded until backups are ready.

- Introduce HA broker state machien
- Inform backup queues when ready.
- Incomplete implementation of backup ready check.
- does not count correctly after a failover, see countUnready.
- Existing replicator bridges updated out of sync with BrokerReplicator initialize.
- Does not handle multi-messages responses.
- Newly promoted HA primary waits for backups to be ready before accepting clients.
- Uniform log prefixes for HA messages.
- qpid-ha tests, call qpid-ha python code directly.
- Move excluder from Backup to HaBroker, it is also used in PROMOTING.

Takes values 'all', 'configuration', 'all'. This is the replication level to use
if a queue or exchange is created without an explicit 'qpid.replicate' argument.

Merged from qpid-3603-7. This is basic support for the new HA approach.
For information & limitations see qpid/cpp/design_docs/new-ha-design.txt.
