Custom Metastore in Presto Connector

[eskrm]

Hi. Does the Presto connector support custom Iceberg SPI implementations? I 
have a table ops implementation that commits to a custom metadata service. The 
Iceberg Spark datasource and catalog support this by extending and overriding a 
protected method to return an Iceberg table/catalog backed by the custom 
implementation. Can anything similar be done here?
