ERROR : "unable to verify user credentials and/or request signature"

Values are mapped same as CloudStack command string formation.
It is generating same signature for both. Noticed difference in CloudStack is cpuSpeed and cpuNumber. In both Speed and Number, first letter in upper case. During signature generation we will convert all the values to lower case.
