Description

What happened?

A Retrofit-based client created via Retrofit2Client.create will send Content-Type: application/json; charset=UTF-8 as a header.

What did you want to happen?

The client should send Content-Type: application/json as specified in the Conjure spec: https://github.com/palantir/conjure/blob/master/docs/spec/wire.md#241-content-type-header

The content-type is set by Retrofit's JacksonRequestBodyConverter, so we'd probably need to make our own version.

Research direction

Start at Retrofit2Client.create and inspect how Retrofit's JacksonRequestBodyConverter sets the JSON Content-Type. Compare the emitted header with the Conjure wire specification, then verify that the client sends application/json without the charset parameter. The issue does not name a test file, so locate the existing Retrofit client request tests before making changes.
