Previously, OpenStack services logged frequent database-has-gone-away errors. This patch adds a parameter that can configure the sql_idle_timeout which can be decreased to reduce these errors. More information on this issue can be found here: https://bugs.launchpad.net/nova/+bug/1007027 for more details. Change-Id: I6e9388b36207be87f7e706be18b4cd4060956a55
