COOPR 542: Add ability to configure UI to use TLS

SSL/TLS implemented for coopr-ui.
These no longer work with the changes to `read_property` above...
```bash
export TRUST_CERT_PATH=`read_property server.ssl.trust.cert.path ${COOPR_SERVER_CONF}/coopr-security.xml`
```
Please, note the `/` after the `${COOPR_SERVER_CONF}` which is required.
