Rodolfo Alonso Hernandez 046672247d Fix queries to retrieve allocations with network_segment_range
Fixed the queries to retrieve the segment ID allocations when service
plugin network_segment_range is enabled. With the previous
implementation, a project user was able to allocate a segment ID
belonging to other project segment range.

The solution implemented was discussed in [1]:
- A project user will retrieve segments from the project ranges.
- When depleted, the segment IDs will be retrieved from the shared
  range, never using another project segment ID.
