Implemented manifest generation for EB full curation in ingest_envoy

Along the way:

• Added tests for partial-curation manifest generation for ingest_envoy
• Separated IngestionManifestBuilder's directory-to-search (staging_source_dir for ingestion, curation_source for curation) from the directory it wants to put its manifest in since partial curation doesn't always have the former.
