This release fixes a bug when there was another logging driver specified than syslog:
Nomad defaults to log-driver=syslog settings and syslog-address=$syslogAddress.
To preserve nomads default behaviour, nomad sets the default values if no logging driver is supplied.
In the previous commit, nomad would always check if there is a field "syslog-address" in the logging options. If not, it would always set this field, yielding in docker do prevent the start as there are wrong logging options when not using "syslog" as logging driver type.
This release addresses this issue and has been tested again syslog, journald json-file and splunk.
