Changed start application method to obtain response headers after a PUT
request is made. The data from the response headers are then returned in
a StartingInfo object. Among the data that is retrieved from the
response headers is the location of the staging log file. Added unit
test case to test the start application that returns a starting
information with the location of the staging log file.
