add ipv6 support to oo-register-dns

thanks to Magnus919bis on irc for the idea
Update oo_deployment_guide_comprehensive.adoc

yum install -y mongodb-server didn't actually install the mongodb package as a dependency, and I had to install it separately. Therefore I have added mongodb to the yum install line to save time/troubleshooting for others.
<docs> Added libmongodb to the yum install command for MongoDB

Bug 1024698

Fix update_cluster to handle the case where a cartridge's minimum
scaling count is >= 2 - treat all web gears except self as new in this
situation.

Don't rotate out when stopping a gear if it's called during the initial
build from post-configure.

Don't check for the force_clean_build marker in prereceive if it's
called during the initial build from post-configure; default to false
instead.

Don't distribute or attempt to do remote activations during an initial
build (this will be taken care of when update-cluster is invoked
afterward).
