JOC servlet should not set SSLContext, if http request only is received

Current Situation

Currently the JocServletContainer tries to always set an SSLContext. This results in a NPE if keystore/truststore settings are configured in the joc.properties file, but the Web Server operates with http.

Desired Behavior

Even a misconfiguration like above should not result in an error. The JocServletContainer should not try to set an SSL Context for a http base Url.

Maintainer Notes
This issue is dismissed. Users who do not want to use https should drop the respective configuration.
