Add option to create a connection eviction thread for a non-shared connection manager

In the tutorial:
http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html, section 2.5 Connection eviction policy - you explain how to clean-up connections. Although I can argue against the design as without this if server closes connections, my client gets many sockets stuck on CLOSE_WAIT - adding this thread solves the CLOSE_WAIT issue.

However, I don't understand why you don't do this yourself if keep-alive is set. I would expect the library to support such a thread. In the meanwhile, it seems that if I use the default connection manager, I can't use non-deprecated code to call :

connMgr.closeExpiredConnections();
and
connMgr.closeIdleConnections(30, TimeUnit.SECONDS);

This is because the only exposed API to get the default pooling connection manager is by calling:

httpClient.getConnectionManager(), which is deprecated. Javadoc suggests to go to the builder (which I do use but not for creating connection pool as the default is good enough for me) which is useless.

So - how should one acquire a reference to the connection manager?
