> 1. Allowing dictionaries in dictionaries is very nessaccary since, configurations we
will recieve from json have a lot of that.
> 2. We need to add default prefixes feature, because our configuration names are pretty
huge, which will result in a very messy code
> How it is now:
> {code}
> "${clusterHostInfo:configurations:yarn-site:yarn.log.server.url}"
> {code}
> how it should be:
> {code}
> env.set_default_prefixes(['clusterHostInfo.configurations.yarn-site',...])
> "${yarn.log.server.url}"
> {code}
