LPS benchmark test 3

[dantewang]

• Step 1, Add benchmark test util
• Step 2 Add integration test to catch regression
• Step 3 Add unit test to do benchmark locally
• Step 4, Run test in a thread pool in parallel, read threadCount and runCount from system properties.
• Step 5, fetch test users and company host names from database
• Simplify the query
• Properly handle user data selection
• Copy ThreadLocalCookieStore and SimpleCookieStore from benchmark project history. The JDK's default Cookie store does not support multi-threading, resulting in cookie errors if executing Login concurrently.
