feat(cli): Update the create pr cli to import layer based on filename.

The reason I don't want the individual flag,

• This makes argo workflow harder to use flag parameter as --individual means true instead of --individual true. We need a if condition in argo to determine whether to add the --individual flag instead of just pass the true as parameter.

• Another reason is once we use the filename, this makes use better to manage if we have more different configs like import the imagery into historical.json config directly. So we just use --finename historical
