Support Publishers for multipart data in BodyInserters [SPR-16307]

[spring-projects-issues]

Marc-Christian Schulze opened SPR-16307 and commented

In order to stream content into a MultipartRequest it would be nice to have support for Publisher, e.g.:

Publisher<ByteBuffer> publisher = ...

WebClient 
    .create(someUrl) 
    .post() 
    .uri(URI.create("/whatever")) 
    .body(BodyInserters.fromMultipartData("file", publisher))
    ...

Reopening, as storing the ResolvableType in the HttpEntity might not be the best way to implement this.

Fixed by moving the ResolvableType to a new HttpEntity subtype: 6c3a645
