Adds a `weight` load variant, which weights an inner load. This is useful in circumstances where it is desireable to artificially inflate or deflate load. One such example is canary deployments, where it might be preferable for a canary to accept less load than its non-canary counterparts. This change is adapted from the weight implementation that used to exist within tower but was removed (see tower-rs/tower@a496fbf) and an associated unmerged PR (tower-rs#282).
