> Change setErasureCodingPolicy to take a required string EC policy name

>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: erasure-coding
>    Affects Versions: 3.0.0-alpha1
>            Reporter: Andrew Wang
>            Assignee: Andrew Wang

> The current {{setErasureCodingPolicy}} API takes an optional {{ECPolicy}}. This makes
calling the API harder for clients, since they need to turn a specified name into a policy,
and the set of available EC policies is only available on the NN.
> You can see this awkwardness in the current EC cli set command: it first fetches the
list of EC policies, looks for the one specified by the user, then calls set. This means we
need to issue two RPCs for every set (inefficient), and we need to do validation on the NN
side anyway (extraneous work).
> Since we're phasing out the system default EC policy, it also makes sense to make the
policy a required parameter.
