Release 1.2.2 to Maven Central

Note that 1.2.2 is in libs-release, but not in central.

I gave this a go today but the job got stuck due to not having enough version history for the artifactory-repo resource. I forced a fetch of some more history with fly -t app-broker check-resource -r app-broker-1.2.x/artifactory-repo --from build_number:app-broker-1.2.x-build-6 which allowed the job to trigger, but then it failed with

Caused by: java.lang.IllegalArgumentException: URI is not absolute
	at java.net.URI.toURL(URI.java:1088) ~[na:1.8.0_292]
	at org.springframework.http.client.SimpleClientHttpRequestFactory.createRequest(SimpleClientHttpRequestFactory.java:145) ~[spring-web-5.3.8.jar!/:5.3.8]

I don't really understand the design of the pipeline which makes me worry about triggering this job. It's pulling build_number app-broker-1.2.x-stage-release-2 from Artifactory - shouldn't we be pulling a promoted release? I assume this is the version that was promoted, but still it feels weird. And also the fact that it seems to pull down 1.2.0 and 1.2.2 artifacts does not fill me with the kind of confidence I'd like to have when hitting the big 'make this all public' button...
