I'd like to review PRs related to metallb addon as possible to make
it better, and it would be easy to track related PRs if becoming the
reviewer.

Add proper RBAC for new csi-attacher version

Recently MetalLB becomes one of addons with renaming the options.
This updates MetalLB README.md for this change.

Add additional metadata configuration options to external Openstack CCM (kubernetes-sigs#6338) (#6339)

* Add additional metadata configuration option to external Openstack CCM (kubernetes-sigs#6338)

* Set the variable external_openstack_metadata_search_order undefined by default

This changes MetalLB contrib to one of addons for deploying MetalLB with
Kubernetes cluster deployment. By the default, Kubespray doesn't deploy
MetalLB addon.

Support for Ambassador OSS as an Ingress Controller when
settings `ingress_ambassador_enabled: true`.

We need to specify either external_openstack_tenant_name or
external_openstack_tenant_id. Those values were checked by seeing they
are defined or they have actual values separately.
However those values are always defined because of the following code
of openstack/defaults/main.yml:

external_openstack_tenant_id: "{{ lookup('env','OS_TENANT_ID')| default(lookup('env','OS_PROJECT_ID'),true) }}"
external_openstack_tenant_name: "{{ lookup('env','OS_TENANT_NAME')| default(lookup('env','OS_PROJECT_NAME'),true) }}"

So even if not specifying both values, those checks could not detect
the misconfiguration. This fixes this to detect the misconfiguration.

On OpenStack history, we used to call "tenant" for separeted namespace.
However we use "project" now instead.
Then we have replaced "tenant" with "project". Then all "TENANT" variables
also are renamed to "PROJECT".
This makes Kubespray search "PROJECT" variable also for newer OpenStack
clouds.
