after investigation with Ihar Hrachyshka <ihrachys> we found out the 

openstack need MySQL-python-1.2.5 but EL7 comes with MySQL-python-1.2.3
According to Ihar this commit https://github.com/farcepest/MySQLdb1/commit/87d1145c0d6ee4f5a8ecf6d5c62d2479b9cf27ea  in MySQL-python-1.2.5 solve the problem 
Version-Release number of selected component (if applicable):
CentOS7.1 Openstack from rdo centos7 trunk http://trunk.rdoproject.org/centos7/current/

How reproducible:
1. install openstack with packstack on centos7
2. configure neutron QoS with openstack
3. neutron qos-policy-create test 
4. neutron qos-policy-show test

Steps to Reproduce:
1.
2.
3.

Actual results:
Error in neutron server
manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 3") 'SELECT qos_policies.tenant_id AS qos_policies_tenant_id, qos_policies.id AS qos_policies_id, qos_policies.name AS qos_policies_name, qos_policies.description AS qos_policies_description, qos_policies.shared AS qos_policies_shared \nFROM qos_policies \nWHERE qos_policies.name = %s' ([u'test'],)

Expected results:
neutron qos-policy-show test show should show the qos policy information
