Move security groups and firewall ops to VirtAPI

This patch moves the following network security-related
methods to VirtAPI:

  security_group_get_by_instance()
  security_group_rule_get_by_security_group()
  provider_fw_rule_get_all()

In order to make this change, the _provider_rules() method
of the FirewallDriver was changed from being a staticmethod
to a regular instance method. All uses of it were in the
context of an actual instance, so I saw no reason to keep
it static, which would have complicated the use of the VirtAPI
methods.
