Pagination need to add next/first numbers in meta

[Fryguy]

Right now, meta just has the limit and offset that was requested, but I think we should also add the limit and offset for next, last, etc (i.e. the numeric values for each the links). This makes using clients a lot easier because you don't have to parse the links for the values. I'm picturing something like the following in addition to the links.

{
  "meta": {
    "count": 1000,
    "limit": 100,
    "offset": 0,
    "first": {
      "limit": 100,
      "offset": 0
    },
    "next": {
      "limit": 100,
      "offset": 100
    },
    "last": {
      "limit": 100,
      "offset": 900
    }
}

@Fryguy good to know, but you probably wanted to cc other Martin :) @Hyperkid123

So i actually wanted to create same issue when i started using the pagination in UI. But because of how the PF4 pagination works this is not really necessary and limit + offset is enough. I can definitely imagine that these might be useful but i don't have a real use case for that right now (from UI perspective).

The only scenario this can be issue right now is if the first offset is not 0. I don't expect that ever happen though.

It should be probably added down the line but it is not urgent i think.
