Add support for uploading file via InputStream

Is your enhancement related to a problem? Please describe

This was originally requested by @yaojiqunaer in #3568

Right now uploading a file to kubernetes pod requires file Path as an argument:

Boolean upload = client.pods().inNamespace("default")
          .withName("exwc796")
          .inContainer("nginxrokumar")
          .dir(destFile)
          .upload(source.toPath());

As suggested by @yaojiqunaer it would be nice to have an additional upload(InputStream in) method:

Upload method only support java.nio.file.Path as a local file path, if i use the org.springframework.web.multipart.MultipartFile uploaded files, are unable to get the file(getFile methord is forbit)，so i must write multiPartFIle inputStrem to local disk and then read file as Path . Why not support both Path and InputStream?
