* metadata/coll_config: don't confuse user metadata with collection config, don't display collection config settings as metadata (ukwa/ukwa-pywb#47)
- for collection template, add separate 'coll_config' dict, keep user metadata only in 'metadata' dict (default to empty)
- for static collections, assume metadata is in the 'metadata' dict of collection config
- for dynamic collections, load metadata.yaml into 'metadata' dict
- ensure 'metadata' key is passed to frame_insert
- ensure 'metadata' added consistently in framed and non-framed mode
- tests: update tests to ensure metadata is added consistently
- fuzzymatch: don't match 204 OPTIONS responses, update fuzzymatcher test
