[~mingleizhang] How far along are you with this issue? The variable name does not have to match the key.

> Many new config keys in the TaskManager don't follow the proper naming scheme. We need to clear those up before the release. I would also suggest to keep the key names short, because that makes it easier for users.
> When doing this cleanup pass over the config keys, I would suggest to also make some of the existing keys more hierarchical harmonize them with the common scheme in Flink.
