Set allow_migrate_to_same_host as True by default

After OpenStack was installed with devstack on a single node, cold
migration always failed because the default value of
allow_migrate_to_same_host is False. This means that devstack do not
support cold migrate a VM to a same host by default.

Normally, a developer will set up OpenStack with devstack on a single
node, so it is better that we change this value to True to enable
cold migration with a single node after installed by devstack.
