Capture filename on input type FILE

Breaking Change

To upload a file for an input of type FILE, you should now use the part name for the input and the part filename attribute for the file name.

For example, when using cURL to start an execution for the following flow:

id: file
namespace: company.team

inputs:
  - id: file
    type: FILE

tasks:
  - id: hello
    type: io.kestra.plugin.core.log.Log
    message: "{{inputs.file}}"

Before 0.24 - now deprecated

curl -v "http://localhost:8080/api/v1/executions/company.team/file" \
    -H "Content-Type:multipart/form-data"    \
    -F "files=@/tmp/test.txt;filename=file"

Since 0.24

curl -v "http://localhost:8080/api/v1/executions/company.team/file" \
    -H "Content-Type:multipart/form-data" \
    -F "file=@/tmp/test.txt;filename=test.txt"
