UDP namespace with @ not allowed/supported?

[jdries]

I have a UDP in a namespace with an '@'.

The web editor can not properly load it because the @ and everything after it is dropped. Adding it again manually does trigger correct loading. Not sure if @ is an illegal character for namespace or some other problem?

The implementation should follow the proposal in PR Open-EO/openeo-api#348

In the proposal, @ plus username is meant to be used for user namespaces so it has a special meaning and is not allowed in user ids, I think.

Regexp for user id: ^[\w\-\.~]+$
Regexp for namespaces: ^@?[\w\-\.~]+$

Has been some time since I worked with user namespaces, but if you follow the PR and the regex, it should work.
