* A simple check to see if it is already registered
fixed the original problem
* Also removed the need to have @ConfigurationProperties
on a bean class (unless you want to specify the target name
etc.)
[Fixes#50256421] [bs-130] When actuator app starts the
@ConfigurationProperties are registered with the bean
factory several times
* If the auto config class has a high Order it can check for
an existing transaction manager
* Unit tests added, and checked also witrh petclinic
[Fixes#50064347]
* ManagementProperties and ServerProperties now support an address property
* For example set management.port=9001,management.address=127.0.0.1 to listen
on port 9001 but only for connections from the localhost
[Fixes#49395783]
