Migrate jProtoc and Canteen to grpc-ecosystem

[rmichela]

With the loss of a consistent release sponsor at Salesforce, it's time to move this repo to the grpc-ecosystem org.

Tasks to do:

• Your project is currently hosted in a public repository.
• Your project's license is the Apache license 2.0.
• Your project doesn't depend on third party libraries with copyleft licenses such as AGPL and GPL.
• Your project has a top-level README.md with the following information:
  • Project overview
  • How gRPC is used
  • A list of external project dependencies such as third-party libraries
  • Build instructions
  • Automated tests and test instructions
• Ensure that all project contributors have signed Google's Contributor License Agreement, accepting that all license and patent rights are determined by the CLA under the Apache license.
• Get written signoff from Salesforce
• Once you've addressed all of the requirements listed above, complete and submit a gRPC Ecosystem Project Addition Request Form.
• Update Maven coordinates
• Update Java package names
• Add an explicit module-info.java for Java >9 users
• Secure access to new Maven repository at Sonatype
• Release version 2.x

Hi @rmichela, What's the latest update on the migration of this repo to grpc-ecosystem?

I'm in contact with Google, and have gotten initial by in from there side. Salesforce is being more complicated because releasing a repo involves the loss of IP rights, so lawyers have to be involved. So, working on it.
