Draft implementation for watch support

[ityuhui]

Hi @brendandburns

This is a draft implementation for watch support. We can discuss the design here.

This PR should not be merged because a part of code should be merged to generator repo https://github.com/OpenAPITools/openapi-generator/tree/master/modules/openapi-generator/src/main/resources/C-libcurl

Hi @clearday4

Cloud you please review the design (especially for the examples/watch_list_pod) too?

Append the output of examples/watch_list_pod

Hi @clearday4

Cloud you please review the design (especially for the examples/watch_list_pod) too?

Sure. I'm pleased to review this function. I will add a comment after review.

[ityuhui]

The callback function pointer data_callback_func will be added to api client by this PR https://github.com/OpenAPITools/openapi-generator/pull/7467

[brendandburns]

Great, let's wait for that to merge and then we can get this PR merged too.

[ityuhui]

Hi @brendandburns

The code is updated after data_callback_func is merged from openapi-generator. Could you please review the new code change ? Thanks

[brendandburns]

One small nit and then it's ready to merge.

[ityuhui]

The code change is updated.
