### Description changes: * NestedDataColumnSchema and AutoTypeColumnSchema now accept a NestedCommonFormatColumn as a new 'columnFormatSpec' property, which allows customizing how json and auto columns are compressed, how strings are encoded in dictionaries, etc, on a per column level. The nested column format spec has several properties: objectKeysEncoding, objectStorageEncoding, objectStorageCompression, stringDictionaryEncoding, dictionaryEncodedColumnCompression, longColumnEncoding, longColumnCompression, doubleColumnCompression NestedCommonFormatColumn blends in segment level config from IndexSpec to populate any values not explicitly specified with segment level. * JSON field names can now be stored with front-coding with columnFormatSpec property objectKeysEncoding * Adds 'druid.indexing.formats.nestedColumnFormatSpec' to define a default NestedCommonFormatColumn #### Release note _todo_ <hr> This PR has: - [ ] been self-reviewed. - [ ] added documentation for new or modified features or behaviors. - [ ] a release note entry in the PR description. - [ ] added Javadocs for most classes and all non-trivial methods.
