Extend HttpLogClient functionality.

Add get log entry with audit path and get sth consistency methods to the HTTP log client.
Add tests for these methods.
The pattern of creating a NameValuePair list with two parameters seem very common in this method, consider creating a static helper method to return a List<NameValuePair> , something like this:
List<NameValuePair> createParamsList(String firstParamName, String firstParamValue, String secondParamName, String secondParamValue)
