QPID-4498: HA module should only initialize if requested

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.
