>          Issue Type: Improvement
>          Components: REEF
>    Affects Versions: 0.10

> We frequently have the need to mirror parameters from the Driver Configuration into all
Evaluator configurations. Examples include the job name and network parameters ([REEF-246]
and [REEF-247]).
> The current approach to do so is very cumbersome. We have the parameters injected in
{{o.a.r.runtime.common.driver.evaluator.EvaluatorManager}} and then bind them to the Evaluator
Configuration in {{o.a.r..runtime.common.driver.evaluator.AllocatedEvaluatorImpl#launch}}.
This is error-prone and tedious.
> Instead, we could follow the approach we've taken for files: We support the notion of
global and local files: Global files are made available on all containers (Driver and Evaluator)
in the folder {{reef/global/}} in the working directory of the container. Local files are
made available only on that specific container in the folder {{reef/local}}. 
> We should have global and local Configuration as well, each of which is available separately
for JVM and CLR containers. We can standardize the file names for them in {{o.a.r.runtime.common.files.REEFFileNames}}
to make sure we don't mistype them.
> What do you think?
