Adds an auto_schema flag to Avro/Parquet codecs

[dlvenable]

Description

The current design of the auto-schema generation for the Avro/Parquet codecs will make the default behavior automatically generate a schema. Users may not be aware that this is happening.

This PR adds a new field auto_schema to enable the feature.

Thus, the user can configure a codec as such:

s3:
  codec:
    parquet:
      auto_schema: true
