[Bug]: nebius backend does not work with nebius sdk 0.2.73

[r4victor]

Steps to reproduce

1. Install latest nebius sdk: pip install nebius==0.2.73
2. See that nebius backend can be configured:

[15:03:45] WARNING  dstack._internal.server.services.config:151 Backend nebius  
                    not available and won't be configured. Check that backend   
                    dependencies are installed.  

Actual behaviour

Apparently, nebius sdk 0.2.73 release removed from nebius.aio.authorization.options import options_to_metadata, which broke dstack nebius integration (

dstack/src/dstack/_internal/core/backends/nebius/resources.py

Line 11 in 688e9c8

from nebius.aio.authorization.options import options_to_metadata

).

Ideally, nebius should fix backward compatibility so that older dstack versions continue to work.

Expected behaviour

No response

dstack version

master

Server logs

Additional information

No response

Instead of metadata, authorization options are now passed directly as a separate request parameter.

Moreover, there is a separate authorization timeout just for your case

PS, sorry for the confusion and a breaking change

Fixed nebius/pysdk#120

Leaving this issue open since we'll have to move to the new nebius 0.3 API eventually.
