DATAPLT-1268 Add shortcut for Iceberg-backed Glue Table

[jeffhiltz]

Adds a GlueIcebergTable shortcut for creating AWS Glue tables backed by
Apache Iceberg format. This shortcut supports:

• Full Iceberg schema definition with complex types (list, map, struct)
• Partition specifications for organizing data
• Write order specifications for sorting data within files
• Three table optimizers: retention, compaction, and orphan file deletion

Usage

const cf = require('@mapbox/cloudfriend');                                     
                                                                               
const IcebergTable = new cf.shortcuts.GlueIcebergTable({                       
  LogicalName: 'MyIcebergTable',                                               
  Name: 'my_table',                                                            
  DatabaseName: 'my_database',                                                 
  Location: 's3://my-bucket/my-table/',                                        
  Schema: {                                                                    
    Type: 'struct',                                                            
    Fields: [                                                                  
      { Id: 1, Name: 'col1', Type: 'string', Required: true },                 
      { Id: 2, Name: 'col2', Type: 'int', Required: false }                    
    ]                                                                          
  },                                                                           
  PartitionSpec: {                                                             
    SpecId: 0,                                                                 
    Fields: [{ Name: 'col1_part', SourceId: 1, Transform: 'identity' }]        
  },                                                                           
  EnableOptimizer: true,                                                       
  OptimizerRoleArn: cf.getAtt('OptimizerRole', 'Arn'),                         
  SnapshotRetentionPeriodInDays: 7                                             
});                     

Limitations

Note that CloudFormation does not expose all table optimizer configuration options. For e.g. for orphan file deletion, runRateInHours is not accepted by CFN as an adjustable parameter, at the time of this writing. As such, this shortcut supports a subset of all possible options.

Testing

Tested with mapbox internal stacks.

Just some minor comments.

I approve of the change, but since I originally opened the PR I'm not able to approve it.
