Health list endpoint

[MatiasManevi]

Change

This PR introduces the implementation of the new List endpoint to the Health service in order to list all the services that a certain server is watching to.

It also adds generated files for the endpoint and its tests.

I would like to write some tests too but I couldn't run the test suite as it is as I get some errors, any help is appreciated.

gulpfile.ts:28:19 - error TS2339: Property 'parallel' does not exist on type 'Gulp'.
28 const lint = gulp.parallel(jsCore.lint);
gulpfile.ts:30:20 - error TS2339: Property 'series' does not exist on type 'Gulp'.
30 const build = gulp.series(protobuf.compile, jsCore.compile, jsXds.compile);

If you run npm install and gulp setup in the repository root directory, that should set everything up to be able to run those tests.

Thank you for the guidance!

Running gulp setup is being problematic. Some deps not working

My node version is 22.13.1, I use nvm.

Does this PR depend on unit tests to be "approvable"? I can add the test code and someone else can try to run them?

I think the most likely issue you are seeing is that the git submodules that the setup script expects to be able to use are absent. You can correct that by running git submodule update --init --recursive. Alternatively, you can run a smaller set of install scripts directly, by running npm install in the root directory, in packages/proto-loader, in packages/grpc-js, and in packages/health-check, in that order.

Thank you!, second approach worked (even tho 29 tests fail). I will work on the tests shortly.
