Pagination Support

[swiffer]

We also will then have to think about how to handle pagination. Playing around with the GitHub API for instance I hit a limit of 100 results for page for Security Advisories, so we'd have to request enough pages to fill in the dashboard time range.

I'm definitely looking for help on this.

Any news on this one? It's the same for the GitLab API, currently building a dashboard for evaluating time spend per issue but GitLab has a limit of 60 days so pagination and a way of splitting the requested time period into multiple queries (if user selects more than 60 days) are much appreciated.
