FS-7564 #resolve #comment [mod_rayo] Added new algorithms for offering calls to clients.

   Two new params added to autoload_configs/rayo.conf.xml
     offer-algorithm
       all: offer to all clients (default and old behavior)
       first: offer to first client, fails over to next client in list
       random: offer to random client, fails over to next random client

     offer-timeout-ms
       0: disable
       > 0 and < 120000: time to wait for reply from offer.  On timeout, next client is offered call.
                         If no other clients available, call is rejected.  5000 is default.
