[Artur Barashev]

> SAP complains about SSLSocketNoServerHelloClientShutdown timing out in their test environment (concurrent test execution with high CPU load). This change addresses this issue in 2 ways:
> - Increase default timeout value
> - Allow adjustment of timeout value by setting "test.timeout.factor" system property
