Finish the process of deprecating holder pods by removing Rook's ability
to deploy them. The intent of this change is to make the most
superficial changes possible to accomplish this. There are still
remnants of code in Rook (particularly the CSI controller) that helped
configure or deploy holder pods. Due to the risk of breaking some
features, cleanup work of hose remnants will be deferred for future
work.

Ceph image no longer has `ip` tool installed. Use a different container
image for the daemonset which sets host IPs and routes for multus hosts.

In order to help users check that they have implemented the newly-added
Multus host configuration prerequisites, add a check to the validation
tool to verify connectivity.
Because users who are already running clusters with Multus enabled, add
a flag that allows users to only check for host configuration
prerequisites. This mode will not start the large number of clients that
would normally be started because those clients could disrupt a running
Rook cluster negatively.
Host checking pods require host network access. Many Kubernetes
distributions have pod security features enabled. In order to allow
non-Vanilla distros to run this tool, allow specifying a service account
that pods will run as, which can be configured by the admin to allow
test pods.
