The WFCORE-338 work is going to add the notion of an HC being configured as a Candidate Domain Controller, which is a separate thing from being "master". There are a number of places where LocalHostControllerInfo.isMaster() is being called to make decisions that with WFCORE-338 should really depend on whether the HC is a CDC, not whether it is master. So, we want LHCI to expose whether the HC is a CDC.
I think initially we can have isCandidateDomainController() just return the result of isMaster(). We can add a setter to LocalHostControllerInfoImpl later when we actually make the CDC status independently configurable.
Places that should be updated as part of this task to use isCandidateDomainController() instead of isMaster():
