ReadMe changes : spec.context.resourcegroup

[s0uravd3]

Following are the changes needed in the ReadMe regarding context attributes for a Service in the section "Account context in operator secret and configmap"

• adding the resourcegroup doesn't work as the logs suggests, its still pointing to the resourcegroupid of default group

• ReadMe for context attributes have attributes listed in camelCase but the actual name in the code is in lowercase. Eg: resourceGroup in ReadMe and resourcegroup in the code. On changing the case the Service creation worked.
