> Data source options are stored as a `CaseInsensitiveStringMap` in Scala,
> however, its behavior is inconsistent in Python:
> {code:java}
> class MyDataSource(DataSource):
> def __init__(self, options):
> self.api_key = options.get("API_KEY") # <- This is None
> spark.read.format(..).option("API_KEY", my_key).load(...){code}
> Currently, options will not have this "API_KEY" as everything is converted to
> lowercase on the Scala side. This can be confusing to users.
