[FLINK-9599][rest] RestClient supports FileUploads
This PR is based on a squashed #6178.
## What is the purpose of the change
This PR extends the `RestClient` to allow sending multipart messages
containing files and an optional json payload.
@tillrohrmann Regarding the previously discussed issue about
´EMPTY_LAST_HTTP_CONTENT`, you can reproduce the issue by reverting the change
to the `FileUploadHandler` and running the `RestClientMultipartTest`.
## Brief change log
* rework `FileUploadHandlerTest` into an abstract base class, to re-use
classes for the `RestClient`
## Verifying this change
* add `RequestProcess` interface for hiding differences between
non-/multipart messages
* refactor `RestClient#sendRequest` into `internalSendRequest` that allows
passing a `RequestProcessor`
* see `RestClientMultipartTest`
