Bug 1536924: Migrate previous asset config from master-config.yaml

Copy configuration from master-config.yaml to the openshift-web-console asset config config map.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1536924

TODO:

- [x] Don't overwrite config map if it exists

Follow on:

- [ ] Remove assetConfig from master-config.yaml on upgrades to 3.9
- [ ] Warn about existing extensions that aren't migrated on upgrades
