Fixed auto security group for nova network

Replaced OS::Neutron::SecurityGroup with AWS::EC2::SecurityGroup.
AWS::EC2::SecurityGroup supports both neutron and nova network.
We don't use neutron-specific instructions.

Enabled auto security group in integration tests for hdp2 plugin.

Increased version of heat engine.
