[jopr-dev] avail reports

Through performance testing, we have decided to increase the time agents wait before sending up availability reports and we've increased the quiet time the server allows between receiving avail reports before "backfilling" an agent (that is, marking the platform and all of its resources down). Now, the default will be 5 minutes between avail reports getting sent by the agent (this is configurable, of course, on the agent via the rhq.agent.plugins.availability-scan.period-secs preference). The server will have a default quiet time of 15 minutes - again, configurable - its done using the administration>server configuration>settings page. I checked this into trunk - if anyone see problems let me know... See: http://jira.rhq-project.org/browse/RHQ-1098
