> As part of schema provisioning project we want to allow hybrid model for Row set-based scan framework, namely to allow to pass custom schema metadata which can be partial.
> Currently schema provisioning has SchemaContainer class that contains the following information (can be obtained from metastore, schema file, table function):
> 1. schema represented by org.apache.drill.exec.record.metadata.TupleMetadata
> 2. properties represented by Map<String, String>, can contain information if schema is strict or partial (default is partial) etc.
