Adding options for enabling organizations and locations

An alternative is ```${FOREMAN_USE_ORGANIZATIONS:+--foreman-organizations-enabled=$FOREMAN_USE_ORGANIZATIONS}``` which prepends ```--foreman-locations-enabled=``` to the value if set:
```bash
args="--no-colors -v ${FOREMAN_USE_LOCATIONS:+--foreman-locations-enabled=$FOREMAN_USE_LOCATIONS} ${FOREMAN_USE_ORGANIZATIONS:+--foreman-organizations-enabled=$FOREMAN_USE_ORGANIZATIONS}"
```
