Commit Message

core/config: add new path/header normalization options (#6398)

## Summary
Add 4 new options:

- `normalize_path`
- `merge_slashes`
- `path_with_escaped_slashes_action`
- `headers_with_underscores_action`

The default behavior for handling paths and headers has changed:

- Slashes will now be merged in paths. `/an//example` becomes
`/an/example`
- Incoming requests with paths that have escaped path characters will
now be rejected
- Incoming requests with headers that have underscores will now be
rejected
