Refactor fields to reduce methods number

[bertrandmartel]

target fields to refactor :

• hostname
• port
• uri
• ftp/http

Goal would be to have the same method for httpd & ftp like

• ftp

  startUpload("ftp://speedtest.tele2.net/upload/upload123.txt",1000000)

• http

  startUpload("http://2.testdebit.info/",1000000)
