At this point we have a bug when all existing instances of the SSLConnectionContext share the same SSLManagerInterface instance in `manager` field. This is not correct, because each instance of SSLManagerInterface (SSLManagerOpenSSL) owns its own copy of SSLConfiguration as `_sslConfiguration`.

SSLConfiguration must not be shared between the global manager and each transient manager instance created with specific transient params for inter-cluster communications.

The SSLManagerCoordinator should be enhanced to create a non-global instance of SSLManagerInterface. The `SSLManagerOpenSSL::initSSLContext()` and all methods it invokes should be refactored to be stateless and const.

Thanks mark.benvenuto for explaining the problem.
