Rework search directories for agent-config.json files.
Here is the logic to determine which `agent-config.json` file will be used: 1. from command line option: `--config myConfig.json` 2. `$HOME/.xds/agent/agent-config.json` file 3. `/etc/xds-agent/agent-config.json` file 4. `<xds-agent executable dir>/agent-config.json` file
