issue #580 : support for configured TLS and cipherSuites

[pheenomenon]

This fix is for #580
This PR has fix as per #2 below.

Few options to fix this are:
1] stop setting ConnectionManager and set useSystemProperties() while building HttpClients, in which case HttpClientBuilder will invoke the code to read systemProperties.
reuseStrategyCopy = new SSLConnectionSocketFactory((SSLSocketFactory)SSLSocketFactory.getDefault(), keepAliveStrategyCopy, targetAuthStrategyCopy, (HostnameVerifier)proxyAuthStrategyCopy);

2] Another approach is to update EwsSSLProtocolSocketFactory.build() to support the call to SSLConnectionSocketFactory constructor using SSL protocol and cipherSuite.
