Merge remote-tracking branch 'origin/config_sa_mode' into integration_2024_w45 (!3024)

Browse Source 
Set SA mode as default

- Set standalone (SA) mode as the default.
- Adjust commands in Docker Compose files by removing --sa flags and
  adding --nsa flags where applicable.
- Add a function to verify that only one mode is being used at a time.
- Update all relevant documentation.

## SA setup with OAI NR-UE
The sa flag is used to run gNB in standalone mode.
The standalone mode is the default mode.
In order to run gNB and UE in standalone mode, the `--sa` flag is needed.
It is not necessary to run either the gNB or the UE using the `--sa` flag in the command line for standalone mode.
At the gNB the `--sa` flag does the following:
- The RRC encodes SIB1 according to the configuration file and transmits it through NR-BCCH-DL-SCH.
The default (SA) mode does the following:
- At the gNB:
* The RRC encodes SIB1 according to the configuration file and transmits it through NR-BCCH-DL-SCH.
At the UE the --sa flag will:
- Decode SIB1 and starts the 5G NR Initial Access Procedure for SA:
