Merge branch 'feature-s1-flex' into develop_integration_2018_w_41

Browse Source 
Introduction of S1-flex. It handles multiple PLMN IDs (up to 6) in the SIB as well as the selection of an MME based on the selected PLMN identity.

Major impact: changes on the eNB configuration files:

tracking_area_code = 1;

plmn_list = (
  { mcc = 208; mnc = 94; mnc_length = 2; },
  { mcc = 208; mnc = 95; mnc_length = 2; }
)

See https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/s1-flex-conf-nnsf for more details.
