Bug 19196: Add Koha::REST::Plugin::Pagination

This patch introduces a Mojolicious plugin to be used on the REST api.
It adds a helper method:

add_pagination_headers
======================

When used, it adds a _Link_ header to the reponse with the calculated
values for pagination, and X-Total-Count containing the total results
like this:

    my $params  = $c->validation->output;
    my $patrons = Koha::Patrons->search;
    my $count   = $patrons->count;

    $c->add_pagination_headers({
            total  => $count,
            params => $params )};

To test:
- Run:
  $ sudo koha-shell kohadev
 k$ cd kohaclone
 k$ prove t/Koha/REST/Plugin/Pagination.t
=> SUCCESS: Tests pass!
- Sign off :-D
