http_server : Fix and enable example tests

This introduces the following changes in the example test scripts :
* Dependency on python requests library removed in favor of httplib
* Bug fixed in the logic responsible for receiving and processing http chunked responses
* Default timeouts increased Note : Due to connectivity issues (between runner host and DUT) in the runner environment, some of the advanced_tests are being ignored. These tests are intended for verifying the expected limits of the http_server capabilities, and implement sending and receiving of large HTTP packets and malformed requests, running multiple parallel sessions, etc. It is advised that all these tests be run locally, when making changes or adding new features to this component.
