Updated git submodules

Project: externalapi/nbi master 4a2e0e101c132c2218033b5e381898a6024e34d8

Add variables to set IP address of ONAP components

These variables must be set either inside an `.env` file in the same
folder as docker-compose.yml or via `exports` function of shell.

Currently, 3 (self explanatory) variables must be set:

- SDC_IP
- AAI_IP
- SO_IP
