API needs to change to return a flattened out pipeline list with paths

In Scope

• API needs to change to return a flattened out list with paths at the top level only
• Subfolders should return only their contents (as they do now)
• An option should be allowed to specify that non flattened list is required (but is not the default)
• Should not result in recursing through folders, or load all jobs into memory
• Objects returns should have links/paths that include the folderName/pipelines/subfolderName/pipelines/PipelineName style of naming so the URI can be set and the data loaded
