Description of problem:
[RFE][RGW]: support cross tenant topic management to allow put bucket notifications from other tenant users
lets say we have two cross tenanted users tenantA:user1 and tenantB:user2 and topic1 and bkt1 are created through user1
put bucket notification to bkt1 from user2 is not allowed even after allowing user2 through bucket policy, if we use topic1 arn in the request
the issue boils down to cross tenant topic access is not allowed currently.

if we create topic2 through user2 and use topic2 arn in put bucket notifications request to bkt1, then it is allowed. It is the workaround currently.

Version-Release number of selected component (if applicable):
ceph version 18.2.0-27.el9cp

How reproducible:
always

Steps to Reproduce:
1.deploy rhcs 7.0 ceph cluster
2.create cross tenanted users tenantA:user1 and tenantB:user2
3.create topic1 and bkt1 through user1
4.allow user2 to put bucket notifications to bkt1 using bucket policy
{"Version": "2012-10-17", "Statement": [{"Sid": "Statement", "Effect": "Allow", "Principal": "*", "Action": ["s3:GetBucketNotification", "s3:PutBucketNotification"], "Resource": "arn:aws:s3::tenantA:bkt1"}]}
5.put bucket notifications using user2 client with topic1 arn in the request using below code snippet
import boto3
from botocore.handlers import validate_bucket_name

tenant='tenantA'
bucket='bkt1'

client = boto3.client('s3',
        region_name='default', 
        use_ssl=False, 
        endpoint_url='http://localhost:8000',
        aws_access_key_id='user2accesskey',
        aws_secret_access_key='user2secretkey')

# disabling bucket name validation to allow for the "tenant:bucket" format
client.meta.events.unregister("before-parameter-build.s3", validate_bucket_name)
TopicConfigurations = [
                        {
                            "Id": "notif2",
                            "TopicArn": "arn:aws:sns:default:tenantA:topic1",
                            "Events": ["s3:ObjectCreated:*", "s3:ObjectRemoved:*"],
                        }
                    ]
response = client.put_bucket_notification_configuration(Bucket=f"{tenant}:{bucket}", NotificationConfiguration={"TopicConfigurations": TopicConfigurations})
print(response)

Actual results:
seeing no such key error for put bucket notification request
botocore.errorfactory.NoSuchKey: An error occurred (NoSuchKey) when calling the PutBucketNotificationConfiguration operation: None

Expected results:
putbucket notification request is successful
