resource/cloudflare_list_item: retry list ID fetches

[jacobbednarz]

Updates the functionality used for fetching the individual list item identifiers to include a retry should the result not be an exact match.

This should handle the situations better where a large batch operation is created and takes some time behind the scenes to complete the polling operation.

Closes #3269
