Maybe to keep the semantics of key we could rename get to getRandom() or getKey() if random is just an implementation detail..

This feature introduces load-balancing across multiple WPT locations. The goal is to always choose least loaded region.
Please note that US-based regions are taken into consideration only.
The following configuration options are introduced:
WTP_LS_CACHE_TTL(defaults:10sec) - how long to cache locations and selected location;0means we check best location on every test runWTP_LS_DEFAULT_LOCATION(defaults:IAD_US_01- which location to use in case there is a problem with API and there is nothing selected yetWTP_LS_UPDATE_TIMEOUT- (defaults:20sec) timeout for updating locationsAlso, for better insight there are two new endpoints (both responses served from local cache):
/locations- prints out all locations we consider along with their metrics/locations/current- identifier of the location we currently use as the best one
