Description

If you create a user with some capital letters in the username, Ambari accepts the request and creates a user with the lowercase version of that username. However, if you then do a GET on the original username, Ambari gives a 200 response but an empty response body:

GET /api/v1/users/MixedCase
200 OK
<empty response>

GET /api/v1/users/mixedcase
200 OK
{
  "href" : "https://ambari-8d6c17ae32685572aa82f82b813138a1.cbdptest.com/api/v1/users/mixedcase",
  "Users" : {
    "active" : true,
    "admin" : false,
    "groups" : [ ],
    "ldap_user" : false,
    "user_name" : "mixedcase"
  },
  "widget_layouts" : [ ],
  "privileges" : [ ]
}

Ambari should throw a 404 error at a minimum, but better yet, just lowercase the username requested and return the right user. Since we silently lowercase it on POST, we should do the same on GET, IMO.
