[docker] modify startCodex.sh

- include overridden node name in log output if specified in test
- quote `—log-level` value so that multiple log levels can be specified
- ensure any CLI parameter env vars are passed through to the codex binary, instead of conditionally including them
- add `—persistence`
- add `—validator`
