completely async from the original thread.
Right now it uses a 100ms timer to determine when the request is actaully complete,
but I think this can be removed in the long run with a better mechanism.

Add Clustered proxying support to mod_serf, by using the heartbeats system.
No preconfiguration of cluster members is needed.
Just a config like this:
SerfCluster sweet heartbeat file=/var/cache/apache/hb.dat
SerfCluster sour heartbeat file=/var/cache/apache/cluster2.dat
<Location "/">
SerfPass cluster://sweet
</Location>
<Location "/different_cluster">
SerfPass cluster://sour
</Location>
The location of all possible destination servers is provided by a new
providers interface, that includes configuration checking of the arguments to
the SerfCluster command, solving one of the worst problems with the mod_proxy
load balancer subsystem.
