Hide CloudStack version from XML response when unauthenticated

[gpordeus]

This PR hides the cloudstack version field of XML responses when the caller is unauthenticated (checks if it is SYSTEM account).

It also adds the expose.cloudstack.version.api.list.capabilities to allow hiding the field from the listCapabilities API call and expose.cloudstack.version.api.xml.response to allow hiding the field from XML responses, both are true by default as to not change compatibility.

It does not change the version information in system VMs and VRs.

Fixes: #10072

code looks good @gpordeus , but can I ask you to remove all the log.append() calls and only append sb to log, just before returning at line 211?

Not your doing for sure, but the code looks a bit silly like this.
