Title: Fix/url mapping remove member and rebind

For UrlMapping:
- Converts UrlMapping from groovy to java
- Adds subscription to cluster.MEMBER_REMOVED
- Renames UrlMapping.onManagementMastering to correct name onManagementStarting
- Group.addMember returns boolean, rather than void

Also:
- SoftwareProcessEntity does not set serviceUp in constructor (required for rebinding, so don't temporarily report wrong value)
- Adds NginxController.HTTP_POLL_PERIOD config
