fix(build): use versions of dependencies that are available on maven central

[dbyron-sf]

This effectively combines the autobump PRs for clouddriver, fiat, front50, and spinnaker-gradle-project, along with the maven coordinate change from com.netflix.spinnaker to io.spinnaker.

There are also some other version changes to use dependencies that exist on maven central, though I haven't been able to exercise them much because...

There have been some changes to clouddriver-cloudfoundry that mean we need some tweaks here too. Or at least I get the following compiler errors:

$ ./gradlew build

@rvazquezglez or @zachsmith1 any chance you can make the okhttp/retrofit changes here similar to spinnaker/clouddriver@f11b7b7 ?

[spinnakerbot]

The following commits need their title changed:

@dbyron-sf fixed the CF stuff but looks like there is another issue elsewhere
