If plugin "network_segment_range" is not enabled and a new segment is required, if no segmentation ID is provided in the request, the segmentation ID assigned is randomly retrieved from the non allocated segmentation IDs. The goal is to improve the concurrent network (and segment) creation. If several segments are created in parallel, this random query will return a different segmentation ID to each one, avoiding the database retry request. Closes-Bug: #1920923 Change-Id: Id3f71611a00e69c4f22340ca4d05d95e4373cf69
