Add support for disabling TLS witohut rebuilding docker image

[pavolloffay]

Is your feature request related to a problem? Please describe.

I would like to run docker image opensearchproject/opensearch:1.0.0 without requiring HTTPS

Describe the solution you'd like

Pass environment variable to disable TLS e.g.

docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" -e "http.host=0.0.0.0" -e "plugins.security.disabled:true"  --rm -it opensearchproject/opensearch:1.0.0  

Describe alternatives you've considered

Additional context

Running without TLS is useful for tests and demos.

@pavolloffay Thanks for bringing this up, this is related to a similar discussion we are having #1029 I mentioned this specific issue related to Jaeger and most other OSS projects.

For those who do not know @pavolloffay is a maintainer of both Jaeger and OpenTelemetry.

docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" -e "http.host=0.0.0.0" -e "plugins.security.disabled=true" --rm -it opensearchproject/opensearch:1.0.0

curl http://localhost:9200

works for me! But it disables also RBAC!

You should see something like that in the logs: [2021-08-05T09:32:16,690][WARN ][o.o.s.OpenSearchSecurityPlugin] [xxx] OpenSearch Security plugin installed but disabled. This can expose your configuration (including passwords) to the public.

Doh I have a typo there plugins.security.disabled:true it should be plugins.security.disabled=true
