Rule that use the average/percentile response times
to assign dynamic "weights" per Server which is then used in 
the "Weighted Round Robin" fashion. 
<p>
The basic idea for weighted round robin has been obtained from JCS
The implementation for choosing the endpoint from the list of endpoints
is as follows:Let's assume 4 endpoints:A(wt=10), B(wt=30), C(wt=40), 
D(wt=20). 
<p>
Using the Random API, generate a random number between 1 and10+30+40+20.
Let's assume that the above list is randomized. Based on the weights, we
have intervals as follows:
<p>
1-----10 (A's weight)
<br>
11----40 (A's weight + B's weight)
<br>
41----80 (A's weight + B's weight + C's weight)
<br>
81----100(A's weight + B's weight + C's weight + C's weight)
<p>
Here's the psuedo code for deciding where to send the request:
<p>
if (random_number between 1 &amp; 10) {send request to A;}
<br>
else if (random_number between 11 &amp; 40) {send request to B;}
<br>
else if (random_number between 41 &amp; 80) {send request to C;}
<br>
else if (random_number between 81 &amp; 100) {send request to D;}
<p>
When there is not enough statistics gathered for the servers, this rule
will fall back to use {@link RoundRobinRule}.
