- Now called BrokerOptions
- Added extra getters to Broker so that nothing else needs to know
  about BrokerOptions
- Significantly reduces header coupling as lots of files include
  Broker.h, but now don't need Options.h

Backup will now shut-down with critical error if it receives a connection-forced
while trying to connect to the primary so the problem is obvious.

ha/StatusCheck: don't use the HaBroker outside the StatusCheck constructor
as it may be deleted. Avoids core dump if broker shuts down early while
status check is ongoing.

- Set auth info on status check connections
- Clean up status check loging
- Use realm@username for authentication name (was using just username)

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.

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.
