fix(fs): overwrite symlink in restore cache

In restore cache process, if there already exist a same link in dist folder, turbo will failed with an error:

```bash
error fetching from cache: error moving artifact from cache into XXXXX: symlink ../uuid/dist/bin/uuid XXXXX/dist/node_modules/.bin/uuid: file exists
```

This patch just remove already existed link.

* Make berry.lock fixtures have non-int cacheKey

* Change cacheKey from int to string

* use empty string instead

Hey! 

We've just switched to turborepo and it's awesome :) Thanks for your work!

This re-adds the log message for Remote Caching, but only when tasks are
actually going to execute. The message was removed in d48fcdf
because it was being included in `--dry-run` output, making
`--dry-run=json` output non-machine-readable. By excluding this log
message from dry run output, we solve both problems.

This commit also moves `logWarning()` into CmdBase to match `logError()`.

We have an issue with threading our `AF_UNIX` socket properly through grpc on windows. Disable the daemon attempt on windows while we work out the issue, so that users aren't bothered by the warning that it isn't working.
