While testing the plugin I found various small improvements to do to improve a bit the user experience:

1. Logs are showing that the upload task is starting/finishing while it does nothing (because TOS aren't accepted for example). It's confusing and could let think that an upload happens which isn't the case

Oct 03, 2019 3:17:55 PM hudson.model.AsyncPeriodicWork$1 run
INFO: Started Bundle Upload
Oct 03, 2019 3:17:55 PM hudson.model.AsyncPeriodicWork$1 run
INFO: Finished Bundle Upload. 1 ms

1. The configuration screen could be improved a bit by just reordering some fields (it's confusing to accept the TOS at the bottom of the form while it it is the most important setting. Without accepting the TOS nothing happens)
2. Few messages / sentences could be improved
