Datatracker 10.3.0 deployed: IMPORTANT - note change to the submission tool

[Robert Sparks <rjsparks@xxxxxxxxxxx>]

Datatracker 10.3.0 has been deployed. See 
https://github.com/ietf-tools/datatracker/releases for details.

One major change: Draft submissions through 
https://datatracker.ietf.org/submit/ now use the asynchronous submission 
workflow. When you submit using that form, the resulting page will note, 
with a warning box, that the checks that take time are running 
asynchronously, and that the page will update itself periodically until 
the results of the checks are available.

This solves the issue that many people using the web UI submission 
endpoint have been running into with the Cloudflare proxies timing out 
before the long-running checks finished.

This is the culmination of a great deal of work. Help me thank the 
developers and volunteers that have contributed to it.

A final note - the syncronous API submission endpoint at 
https://datatracker.ietf.org/api/submit has been deprecated for several 
releases in favor of the asynchronous endpoint at 
https://datatracker.ietf.org/api/submission. The use of /api/submit has 
slowed, but it has not yet stopped. If you have scripts you have created 
yourself, or if you are using a very old version of someone else's 
scripts (such as a very old repo created from Martin's template 
repository), please update. If you don't know how to update, ask for 
assistance at tools-discuss@xxxxxxxx. We will remove the /api/submit 
endpoint after IETF 117.
