Description of problem:
When deploying the overcloud using /usr/share/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-rgw.yaml to configure rgw as a drop-in replacement for swift, the swift endpoints are missing AUTH_%(tenant_id)s causing the issue described in https://access.redhat.com/solutions/3228661 to appear.

The issue appears to lie within /usr/share/openstack-tripleo-heat-templates/network/endpoints/endpoint_data.yaml which has this set for swift, but not rgw:
~~~
Swift:
    Internal:
        net_param: SwiftProxy
        uri_suffixes:
            '': /v1/AUTH_%(tenant_id)s
            S3:
    Public:
        net_param: Public
        uri_suffixes:
            '': /v1/AUTH_%(tenant_id)s
            S3:
    Admin:
        net_param: SwiftProxy
        uri_suffixes:
            '':
            S3:
    port: 8080

CephRgw:
    Internal:
        net_param: CephRgw
        uri_suffixes:
            '': /swift/v1
    Public:
        net_param: Public
        uri_suffixes:
            '': /swift/v1
    Admin:
        net_param: CephRgw
        uri_suffixes:
            '': /swift/v1
    port: 8080

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-8.2.0-6.2.el7ost.noarch
ceph-ansible-3.2.8-1.el7cp.noarch

How reproducible:
Each deployment

Steps to Reproduce:
1. Deploy RHOSP 13 with rgw per https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/html-single/deploying_an_overcloud_with_containerized_red_hat_ceph/index#ceph-rgw
2. Attempt to utilize public containers

Actual results:
Receive NoSuchBucket with public containers, swift endpoints are missing AUTH_%(tenant_id)s

Expected results:
Public containers work normally, swift endpoints are complete

Additional info:
Workaround is:
- append "AUTH_%(tenant_id)s" to each of the uri_suffixes in CephRGW in endpoint_data.yaml
- run the builder script build_endpoint_map.py
- re-run the overcloud deployment
