[pve-devel] [PATCH eslint] change from CLIEngine to ESLint

[Dominik Csapak <d.csapak@proxmox.com>]

8.0 officialy removed CLIEngine (though it's still in git) so use
the current and supported API.

Necessary changes:
* use 'ESLint' instead of 'CLIEngine'
* use 'lintFiles' instead of 'executeOnFiles' (thats async now)
* adapt to the change of return value of 'lintFiles'

after appliying this, we have to 'make buildupstream' again, since the
included code changes (CLIEngine -> ESLint)
