ACS 4.21 RC2 doesn't return version in xml response

[rohityadavcloud]

problem

This is API response for 4.21 RC2:

> curl -Ss http://172.20.0.223:8080/client/api
<?xml version="1.0" encoding="UTF-8"?><errorresponse><errorcode>401</errorcode><errortext>unable to verify user credentials and/or request signature</errortext></errorresponse>%

The same for 4.20.1:

curl -Ss http://localhost:8080/client/api
<?xml version="1.0" encoding="UTF-8"?><errorresponse cloud-stack-version="4.20.1.0"><errorcode>401</errorcode><errortext>unable to verify user credentials and/or request signature</errortext></errorresponse

Notice the missing cloud-stack-version="4.20.1.0" in <errorresponse...>

This is fine as long as there is any other way to detect ACS version?
