> Following relationships in hive-model need update:
> - hive_table.columns -> hive_column.table is defined as mappedFromRef.
>   Not all hive_column objects that refer to a table might be included in 'hive_table.columns'
attribute - given few columns might be referenced from hive_table.partitionKeys. This would
require hive_table.columns to be modeled with foreignKey constraint, as shown below:
>   hive_table.columns -> hive_column foreignKey
> - Also attributes hive_table.columns and hive_table.partitionKeys should automatically
be updated when a column referenced is deleted. Model should be updated to mark the foreignKey
constraint with "onDelete=update" param.
