Add Jira Agile support

[Stephen Clarke]

How would you feel about adding support for some (or all) of the Agile API?

JIRA Agile REST API

I'm particularly interested in working with boards and sprints. I have tested using the API with jira.RestClient.ExecuteRequestAsync and it works as expected. I think the main decision would be if/how you'd want to integrate it.

Again, I'm happy to get involved but figured it's easier to discuss it upfront.

I am ok with adding support for it. I already added support for the "Sprint" custom field that was needed by another user.

Could you write a proposal of how the API would look like from the consumer's perspective?

Thanks.

This would be great. Something like Jira.Sprints.GetSprintAsync(int sprintId) that corresponds to GET /rest/agile/1.0/sprint/{sprintId}. Also something like Jira.Sprints.GetActiveSprintsAsync() returning all where State != closed.

I'm fine with querying issues for a sprint as can already be done with issue queries and ["Sprint"] and just having this return the basic sprint data like:

"id": 37, "self": "http://www.example.com/jira/rest/agile/1.0/sprint/23", "state": "closed", "name": "sprint 1", "startDate": "2015-04-11T15:22:00.000+10:00", "endDate": "2015-04-20T01:22:00.000+10:00", "completeDate": "2015-04-20T11:04:00.000+10:00", "originBoardId": 5, "goal": "sprint 1 goal"

Support for JIRA agile is a big task that I do not have plans to undertake at the moment. If anybody is interested in working on this a submit a PR I would be happy to work with them on ideas to implement as well as patterns so that the library remains consistent.
