View object versions in the cloudstack object storage

##### ISSUE TYPE

* Bug Report
* Improvement Request

##### COMPONENT NAME

~~~
Cloudstack Object storage
~~~

##### CLOUDSTACK VERSION

~~~
4.19
~~~

##### CONFIGURATION

Cloudstack object storage was added to 4.19, using the MinIO.

##### OS / ENVIRONMENT

MinIO

##### SUMMARY

Although CSOS allows the creation of buckets with versioning enabled it can't operate on the versions. Since the versions are not accessible through the object storage UI we can't delete a bucket with versioning enabled if there are older versions of the objects still present. This is could be handled by using MinIO directly but it would be good to have it done using cloudstack itself.

##### STEPS TO REPRODUCE

~~~
1. Create a MinIO server
2. Add the minIO server to cloudstack as object storage
3. Add a bucket with versioning enabled
4. Upload an object
5. Upload a new version of the object
6. verify that the older version is not listed
7. Delete all the objects and delete the bucket

~~~

Reproduce the workflow with a MinIO server registered as CloudStack object storage, then inspect the existing object-storage UI and its bucket and object operations. Compare behavior for a versioned bucket and define done as showing object versions and allowing the older versions to be handled so the bucket can be deleted through CloudStack.
