Add an HTTPS template for Tomcat

Create an HTTPS template for configuring Tomcat to directly listen to HTTPS, instead of relying on an HTTP server.

In conf/server.xml and server.xml.nx

Put between comments the sections:
<Connector port="${nuxeo.server.http.port}" protocol="HTTP/1.1" address="${nuxeo.bind.address}"
connectionTimeout="20000" redirectPort="${nuxeo.server.https.port}" />
<Connector port="${nuxeo.server.ajp.port}" protocol="AJP/1.3" address="${nuxeo.bind.address}"
redirectPort="${nuxeo.server.https.port}" />

Remove the comments and add certificate info to the section:
<Connector port="${nuxeo.server.https.port}" protocol="HTTP/1.1" SSLEnabled="true"
address="${nuxeo.bind.address}" maxThreads="150" scheme="https" secure="true"
keystoreFile="/path/to/keystore" keystorePass="password" clientAuth="false" sslProtocol="TLS" />

Set default values for nuxeo.url (https://localhost:8443/nuxeo), nuxeo.loopback.url and opensocial.gadgets.port in nuxeo.defaults
