Source based routing is necessary for some services where we want the
same clients land to the same servers.
For exanmple, Keystone uses one of many memcached servers - if a client
gets a token from one but then lands on another api server on the next
request, that will bind to another cache and we get failed
authentication.
Other examples are horizon/murano where we upload a package in several
steps. If we don't balance client connections to the same host we will
end up with the package downloaded to one host but unsuccessfully
unpacked/imported on another host.
This option is commonly used in the official OpenStack docs [0]

Currently the project-deploy-guide links to the entire dev
doc repo for Kolla-Ansible. This is incorrect. It should link
only to installation information that can be found in the quick
start guide. This patch remedies that change, and ensures that
there is a link to the kolla deploy guide published at
docs.o.o.

cinder-volume will be hanged if rados_connect_timeout is disabled. And
no error message will be thrown. Disable timeout is not a good idea.
This patch sets the rados_connect_timeout to 5.
