[API] Add params to milestone API with order

[mmarif4u]

Current milestone API return both closed and open milestones, /repos/{owner}/{repo}/milestones.

It would be useful if it accept params to filter close and open milestones easily with order will be plus.
Open:
/repos/{owner}/{repo}/milestones?status=open&order=desc

Closed:
/repos/{owner}/{repo}/milestones?status=close&order=desc

Is it currently possible to get closed milestones by using API? I have tried with ?state=closed, and
?status=closed but without luck 😢

I am using latest from master.

Don’t think that’s possible yet as no one has worked on this

@mmarif4u I just checked and that endpoint returns only opened milestones since #5051 .

@esfraner I will make a PR to add the state params to the API like that of GitHub

See https://developer.github.com/v3/issues/milestones/#list-milestones-for-a-repository and #5051 (comment)
