QPID-5482: HA Backup becomes useless if a connection-forced error is raised.

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.

> If the cluster is mis-configured so that backups do not have access to the primary (e.g.
by using an ACL that does not provide full access to the ha-username) then the primary will
close attempted connections with a connection-forced error.
> This will close the backup link, so it no longer attempts to connect, rendering the backup
useless. There is a warning message but its not obvious that this indicates a fatal problem:
