Deprecate archive.sh script -> use `./console core:archive` instead

[mattab]

The script archive.sh was the first way we implemented auto archive.

It has been replaced by the new console command ./console core:archive --url=http://x

The script should output a warning message and error, so that user know to change the cron.

In 5a233b5: Fixes #5039 Deprecate archive.sh by printing warning message, returning error, and still we try to stay backward compatible by running ./console core:archive
