Summary:                    [PATCH] Add a new queue strategy: weighted random
(wrandom)
Description: 
Random strategy, but using penaly as a weight. Basically, the higher the
penalty, the less probability to receive calls from the queue.

[600]
strategy=wrandom
member=SIP/100,0
member=SIP/101,1
member=SIP/102,2

When calculating the metric for each round, we use this formula:
metric=ast_random() % ((penalty+1)*1000)

penalty 0 => metric between 0 and 999
penalty 1 => metric between 0 and 1999
penalty 2 => metric between 0 and 2999

The member with lower metric gets the next call.

I think this strategy=wrandom can be really useful.
