Paging response results and metadata

[fmigneault]

Results returned from following routes should support paging and add additional metadata:

• GET /processes
• GET /proceses/{id}/jobs

Additional paging metadata should be defined as in follow:

{
    <...>, 
    "links": [
    { "href": "<this_url_path>?page=<page>&limit=<limit>",
      "rel": "self", 
      "type": "application/json", 
      "title": "This page results" },
    { "href": "<this_url_path>?page=0&limit=<limit>",
      "rel": "first", 
      "type": "application/json", 
      "title": "This page results" },
    { "href": "<this_url_path>?page=<page-1>&limit=<limit>",
      "rel": "prev", 
      "type": "application/json", 
      "title": "Previous page results" },
    { "href": "<this_url_path>?page=<page+1>&limit=<limit>",
      "rel": "next", 
      "type": "application/json", 
      "title": "Next page results" },
    { "href": "<this_url_path>?page=<max(page)>&limit=<limit>",
      "rel": "last", 
      "type": "application/json", 
      "title": "Last page results" }
  ]
}
