HttpBody mesage feature for stream RPC

[adasari]

It is same as #1268, but target branch is v2.

@johanbrandhorst fuzzit and node_test failures are not related to changes. can you take a look at them ? thanks.

[adasari]

@johanbrandhorst each stream header includes from http body now. please review.
Also, can you elaborate #1268 (comment) ? i couldn't understand what you are referring to.

[adasari]

fuzzit and node_tests successful now. not sure what caused the issues.

[johanbrandhorst]

Great work starting this! Could we also add a section to the HttpBody documentation that we support streams now?

can we take updating HTTPBody documentation as separate PR/MR ? can also share me where i can update the doc ? thanks.

[johanbrandhorst]

Almost there, but could you please add something to the httpbody docs? They are here: https://github.com/grpc-ecosystem/grpc-gateway/blob/v2/docs/_docs/httpbody.md.

[adasari]

the httpbody.md is not updated as per v2. do you want me add stream example to the same one ?
