Add Default Compression Codec Specification for Columns in config.xml

Why it matters

This feature allows users to configure a default compression codec for columns across tables by setting it in the server configuration file (config.xml). It simplifies managing compression settings and ensures consistent compression behavior without needing to specify codecs explicitly in table definitions.

How to use it

To use this feature, add or modify the Default compression codec setting under the appropriate section in the config.xml file. This setting will then be applied as the default codec for columns that do not have an explicitly defined codec.
