Add/remove double quotes in path

[MikeKutz]

As a developer using JSON Utils
I need to be able to convert a JSON Path between usage for json_object_t and JSON data types
because

• some tasks are easier with json_object_t
• some tasks are easier with JSON
• JSON only supports valid SQL names for JSON Path (needs "some-path")
  = json_object_t does not (needs some-path )

Results

• JSON_Path_utils.add_double_quotes_to_path is created and works
• JSON_Path_utils.remove-double_quotes_from_path is created and works
• UT updated (or created
