System models are read only models for implementing part of the system's functionality,
and for providing access to information about how the system is working.
Usage example::
from infi.clickhouse_orm.database import Database
from infi.clickhouse_orm.system_models import SystemPart
db = Database('my_test_db', db_url='http://192.168.1.1:8050', username='scott', password='tiger')
partitions = SystemPart.get_active(db, conditions='') # Getting all active partitions of the database
if len(partitions) > 0:
partitions = sorted(partitions, key=lambda obj: obj.name) # Partition name is YYYYMM, so we can sort so
partitions[0].freeze(db) # Make a backup in /opt/clickhouse/shadow directory
partitions[0].drop() # Dropped partition

``Note``: system.parts stores information for all databases. To be correct,
SystemPart model was designed to receive only given database parts.
