EPSDK API should allow caller to specify keystore and truststore for SSL/TLS connections

When Control Center is configured for SSL, an application using the EPSDK should be able to specify the keystore and truststore to use for SSL connections.

Currently the EPSDK does a few things that don't work well

1. The SDK sets up a Trust Manager that trusts All SSL certificates. This is very insecure.

2. The SDK uses the APIs HttpsURLConnection.setDefaultHostnameVerifier(..) and HttpsURLConnection.setDefaultSSLSocketFactory(..). These set SSL settings for ALL HTTPs connections in the application. If there are other parts of the application that rely on these APIs, they could override the settings the EPSDK wants to use and cause problems. We have seen this in our application and it took days to figure out why our Control Center events were not being sent.

The ask is:

1. Do not Trust All SSL Certificates. The API should provide an option to provide a keystore and trust store that should be used for HTTPs connections to Control Center. Additionally some other options like the ability to control hostname verification would be good.

2. Do not use HttpsURLConnection.setDefaultHostnameVerifier(..) and HttpsURLConnection.setDefaultSSLSocketFactory(..). The EPSDK should set SSL settings only for the connection it is making. Any SSL settings for the EPSDK should not affect SSL settings for other HTTP connections.
