Locator is an https webservice that returns hosts ip addresses for a given server tag and user.
Locator client APIs will use /etc/bm/bm.ini to figure out where locator is installed.
When a LocatorClient is created, two properties from bm.ini will be considered.
Once the ip is figured out, the final url will be https://[ip]:8084/
A GET http query to https://[ip]:firstname.lastname@example.org will return a text/plain document with the ip address of an host with the bm/core tag usable for the admin user in the willow.vmw domain.
