On primary a PrimaryTxObserver observes a transaction's TxBuffer and generates
transaction events on a tx-replication-queue. On the backup a TxReplicator
receives the events and constructs a TxBuffer equivalent to the one in the
primary.
Unfinished:
- Primary does not wait for backups to prepare() before committing.
- All connected backups are assumed to be in the transaction, there are race
conditions around brokers joining/leavinv where this assumption is invalid.
- Need more tests.

Many HA tests use --port=0 to start a broker on an available port, but then need
to shutdown and restart the broker on the same port. This is not safe, on a busy
system it is possible for another process to take the port between the time the
broker is shut down and the time it is restarted.
The solution is to do bind(0) and listen in the python test framework (class
HaPort) and let the broker use the socket using qpidd --socket-fd. When the
broker is shut down the port remains bound by the python process. When the
broker is re-started it again is given access to the socket via --socket-fd.
Other changes
- move ha_store_tests into ha_tests.
- add heartbeats to avoid stalling.

Bug in StatusCheck, was setting fetch timeout to uninitialized value
which was sometimes 0, causing an immediate timeout of fetch.

HA brokers need to know their own addresses, but it is not safe to simply use
local hosts name and Broker::getPort() since the broker may be listening on
multiple addresses. The solution is to have brokers check the ha-rokers-url for
their own address while doing the initial status check of the cluster.

allowing sub-second intervals.
Provides string conversion for sys::Duration, allowing intervals to be expressed like this:
10.5 - value in seconds, backward compatible.
10.5s - value in seconds
10.5ms - value in milliseconds
10.5us - value in microseconds
10.5ns - value in nanoseconds
Converted the folllowing broker options to Duration:
mgmtPubInterval, queueCleanInterval, linkMaintenanceInterval, linkHeartbeatInterval
Did not convert: maxNegotiateTime. This is expressed in milliseconds so it would not be
backward compatible to make it a Duration.

Was seeing core dumps with QueueReplicator::queue == 0. Caused by race
conditions when calling QueueReplicator::deactivate. Renamed deactivate to
destroy and call it only when the broker::Queue is destroyed.

A joining broker now attempts to contact all known members of the cluster and
check their status. If any brokers are in a state other than "joining" the
broker will refuse to promote. This will allow rgmanager to continue to try
addresses till it finds a ready brokers.
Note this reqiures ha-brokers-url to be a list of all known brokers, not a
virtual IP. ha-public-url can still be a VIP.
