REST: Allow specifying the page size
The current REST interface only allows getting 20 results per query, which leads to a lot of requests and poor performance when the network latency is high. Allowing a page size of 100 would still remain reasonable on the database and would increase by 5x the loading time of a js-based tool to show latencies.
For some inspiration, here is what I did for cibuglog: https://gitlab.freedesktop.org/gfx-ci/cibuglog/-/blob/master/CIResults/rest_views.py#L27
