[BUG] - Raise an error in the UI if env name is too long

[nkaretnikov]

Describe the bug

• Create an env containing 255 a chars: 'a' * 255
• It hits a 255 char filename limit on my Linux fs and is a common limit on many other filesystems: https://serverfault.com/questions/9546/filename-length-limits-on-linux
• Backend throws:

OSError: [Errno 36] File name too long: '/home/nkaretnikov/.conda-store/storage/logs/804c728fbcd3f510b399fc7b1e12de61061008766f8d0b6815542305ded59906-20231106-180635-533958-1-aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.log'

(This is with a local backend with uses the FS. With a different backend, the error might be different, but the problem is the same - we need to communicate errors.)

Expected behavior

An error is shown in the UI. I think the solution here is to check some API after N seconds, but only if the package is in the Building status (this will avoid a race condition where multiple things are Queued). If the API fails, mark the whole build as Failed, too.

What happens instead is that UI keeps spinning in the Builds state.

How to Reproduce the problem?

See above.

Alternatively, it might be possible to report the status as part of the initial call when a build is created. That would be best, since it's less racy, but not sure if it's possible.

Clicking on the Create button
-> api_post_specification
-> register_environment
-> create_build.

In create_build, DB operations are done, then an async task is launched. Because the task is async and might be in the Queued state, we don't block and return the build id.

So the solution here might be catching errors in the the task and updating build state to Failed.

Status update: in review, will be fixed as part of https://github.com/conda-incubator/conda-store/pull/653/commits (Set status to FAILED in build_conda_environment)
