[Feature]: Support `dstackignore` (similar to `.gitignore`)

[peterschmidt85]

Problem

In some cases, .gitignore cannot be used, e.g. when users want to push large local files to Git eventually and don't want to list them in .gitignore. At the same time, they don't want to upload them via dstack apply.

Solution

Support .dstackignore (in addition to .gitignore).

Workaround

Use --no-repo with dstack init. But this will only work when you don't want to upload any files.
