This commit adds infrastruture for repmgr to be able to check whether one standby can attach to another node, regardless whether it is a standby or a primary. This is intended to prevent a node from attempting to follow a node whose timeline has diverged. The --dry-run option makes it possible to test a follow operation before it is carried out. As a useful side-effect this makes it possible for a standby to follow another standby. This is an initial implementation; documentation and possibly further changes to follow.
