def get_tables():
tables = [<EOL>'<STR_LIT>',<EOL>'<STR_LIT>',<EOL>'<STR_LIT>',<EOL>'<STR_LIT>',<EOL>]<EOL>return tables<EOL>
Returns hardcoded list of tables which have ``tenant_id`` column.
DB head can be changed. To prevent possible problems, when models will be
updated, return hardcoded list of tables, up-to-date for this day.
Output retrieved by using:
>>> metadata = head.get_metadata()
>>> all_tables = metadata.sorted_tables
>>> tenant_tables = []
>>> for table in all_tables:
...     for column in table.columns:
...         if column.name == 'tenant_id':
...             tenant_tables.append((table, column))
