Currently only next Link header is generated in blueocean API response for collection APIs.

To support previous in UI, we need previous (rel="prev") HTTP Link header parameter in blueocean response as well.

Refer to PagedResponse.

Link:</blue/rest/organizations/?start=100&limit=100>; rel="next",
      </blue/rest/organizations/?start=0&limit=100>; rel="prev"

• Generate prev Link parameter only for pages > 1
• Generate next Link parameter only for pages != total-page-size or when its not last page
• Write tests to validate start, prev and next values
