Add 2-node cluster of OpenSearch docker containers to development docker deployment

[naknomum]

Adds to development docker configuration a 2-node OpenSearch cluster, per #510

Notes

• Using only single node for development
• Development-only settings which very likely should be changed for eventual production docker deploy:
  • ports 9200, 9300 exposed for direct localhost access
  • plugins.security.disabled=true in order to disable SSL usage for http://localhost:9200 exposure (above); removing this will require additional SSL/cert magic to happen
• Connectivity from wildbook docker container confirmed via curl access, see below.

really a false-positive as this is a development-only password and meant just to fulfill the requirement of having some password in order to launch OpenSearch. i have closed the gitguardian incident.
