Is it intended that we require METRON_LDAP_PASSWORD when LDAP isn't in use
to start metron-rest?
```
[metroniso@server ~]$ export METRON_LDAP_PASSWORD=anything
[metroniso@server ~]$ /usr/metron/0.7.0/bin/metron-rest.sh
[metroniso@server ~]$ tail -f /var/log/metron/metron-rest.log
# No error
```
```
[metroniso@server ~]$ unset METRON_LDAP_PASSWORD
[metroniso@server ~]$ /usr/metron/0.7.0/bin/metron-rest.sh >/dev/null
[metroniso@server ~]$ tail -f /var/log/metron/metron-rest.log
