lgtm. Think we can take this out of draft and merge as is unless you were planning to add more? :)

@javier-aliaga thanks a lot for documenting this. Could you please add the Java property approach alongside the env vars one.

[artur-ciocanu]

@javier-aliaga for completeness you should mention that GRPC TLS related configs can be passed either via env vars or Java properties.

Here are the property names corresponding to env vars:

• dapr.grpc.tls.insecure
• dapr.grpc.tls.ca.path
• dapr.grpc.tls.cert.path
• dapr.grpc.tls.key.path

I ended up opening this PR to address the lack of documentation and fix the system properties aligning with the env vars. If we like the approach I took in my PR we can close this one out.

[artur-ciocanu]

@javier-aliaga could you please close this PR. @cicoyle merged all the necessary changes related to GRPC env vars and System Properties and has updated the docs.

[cicoyle]

Closing this since we merged in the above linked PR docs. Thanks for the start on it here! I wanted to pull it out and expand this content.
