 * and trello_listid with scope=user,web.
 * 
 * Trello board list IDs can be retrieved via API:
 * https://api.trello.com/1/boards/{BOARDID}/lists?key={KEY}&token={TOKEN}
 * 
 * Example Terminus command:
 * terminus secret:site:set {SITE} trello_listid {LISTID} --scope=user,web
 * terminus secret:site:set {SITE}.test trello_listid {LISTID} --scope=user,web
