Fix wforce docker image issue

[neilcook]

• Image was using the sample wforce and trackalerrt config files instead of "no"config file as should be the case
• Generate the console/replication key from kernel random uuid rather than try to use wforce itself to generate it (which can lead to a deadlock)
• Don't use deprecated version of webserver listen command when generating config
• Test wforce image properly in regression (previously some tests were failing but not being picked up)
• Test trackalert binary in regression
