 """ This formatter will take a data structure that represent a tree and will print all the paths from the root to the leaves in our case it will print each value and the keys that needed to get to it, for example: vm0: net: lago memory: 1024 will be output as: vm0/net/lago vm0/memory/1024 Args: info_dict (dict):
 information to reformat delimiter (str):
 a delimiter for the path components Returns: str: String representing the formatted info """
