Deprecate and remove obsolete DC apis

[0xmichalis]

I am not sure if we ever deprecated officially generatedeploymentconfigs and deploymentconfigrollbacks but we should do it at some point.

@jwforres Looks like the console is using deploymentconfigrollbacks

[jwforres]

@mfojtik @Kargakis what should we move to in order to replace deployment config rollbacks?

[0xmichalis]

@jwforres deploymentconfigs/{name}/rollback

[mfojtik]

@Kargakis @smarterclayton is this v2 item? i mean once we draft v2 API, we can deprecate these.

@openshift/api-review FYI
