enb: Set cipher and integrity via scenario file
This patch enables setting cipher and integrity algorithms
in Amarisoft eNB and srsENB via scenario files. If no
settings are defined following defaults are applied:
- Cipher algorithm: EEA0, EEA2, EEA1
- Integrity algorithm: EIA2, EIA1, EIA0
Example of setting cipher algorithms:
- 4g:srsue-rftype@uhd+srsenb-rftype@uhd+mod-enb-cipher@eea1+mod-enb-cipher@eea0+mod-enb-nprb@6
