feat: allow expiration of all versions via ILM Expiration action (#17521)

Following extension allows users to specify immediate purge of
all versions as soon as the latest version of this object has
expired.

```
<LifecycleConfiguration>
    <Rule>
        <ID>ClassADocRule</ID>
        <Filter>
           <Prefix>classA/</Prefix>
        </Filter>
        <Status>Enabled</Status>
        <Expiration>
             <Days>3650</Days>
	     <ExpiredObjectAllVersions>true</ExpiredObjectAllVersions>
        </Expiration>
    </Rule>
