Create synchronized indicator for Security Group, EC2 and RDS instances

[Lyz]

Create a report to monitor that the desired security groups for EC2 and RDS meet the actual ones as well as the security rules in the security groups.

In the security groups is done by at creation copying the rule definitions in the user_data.yaml, assuming that the user is going to review them and accept them as the desired state.

We'll have to add the same info in the EC2 and RDS user data, adopt the sync method from the SecurityGroup class and create a sync report that will output which ones aren't synchronized
