Remove the files in path.  Unlike |purge| it obeys include/exclude
filters so can be used to selectively delete files.

|rclone delete| only deletes files but leaves the directory structure
alone. If you want to delete a directory and all of its contents use
the |purge| command.

If you supply the |--rmdirs| flag, it will remove all empty directories along with it.
You can also use the separate command |rmdir| or |rmdirs| to
delete empty directories only.

For example, to delete all files bigger than 100 MiB, you may first want to
check what would be deleted (use either):

    rclone --min-size 100M lsl remote:path
    rclone --dry-run --min-size 100M delete remote:path

Then proceed with the actual delete:

    rclone --min-size 100M delete remote:path

That reads "delete everything with a minimum size of 100 MiB", hence
delete all files bigger than 100 MiB.

**Important**: Since this can cause data loss, test first with the
|--dry-run| or the |--interactive|/|-i| flag.
