Fix Nuxeo Tomcat HTTPS Configuration

When testing a third-party integration, we needed to configure an HTTPS configuration (requirement of the addon). But we cannot find a running HTTPS Nuxeo configuration

Step to reproduce:

• Follow https://doc.nuxeo.com/nxdoc/http-and-https-reverse-proxy-configuration/

In the nuxeo.conf file

nuxeo.server.https.port=8443
nuxeo.server.https.keystoreFile=/Users/gregorycarlin/keys/my-release-key.keystore
nuxeo.server.https.keystorePass=Nuxeo2017!
nuxeo.templates=default,https

The server can't run and says :

nuxeo_1  | WARNING: Catalina.start using conf/server.xml: Error at (106, 25) :
Multiple SSLHostConfig elements were provided for the host name [_default_].
Host names must be unique.

It seems we are using deprecated attribute according to https://stackoverflow.com/questions/42135892/tomcat-8-5-server-xml-multiple-sslhostconfig-elements-were-provided-for-the-ho#45496152

It looks like it's related to the version of Tomcat we're using
