Commit c27e317b217391336b0b63c19bf537a5e02377d3 by Pau Espin Pedrol
Introduce hashtable to lookup session by F-TEID

This is a hot path when creating new sessions. Previous code would take
ages specially when UPF already had thousands of sessions created and a
new TEID to allocate was being looked up.
