Refactoring of the object model for connection/security groups so that a
SecurityGroup object can be used as the target of an .allowTo()
statement:

cluster.connections.allowTo(securityGroup)

Also add SecurityGroupRef.import to allow importing a non-constructed
SecurityGroup into the construct tree.

As part of the refactoring:

  • Get rid of IDefaultConnectable, the functionality has been folded into
    IConnectable/Connections.
  • Get rid of ISecurityGroup.
  • Rename IConnectionPeer => ISecurityGroupRule.
  • Drastically simplify implementation, get rid of recursion and classes
    to enable the recursion to terminate. All complex logic is now nicely
    contained within Connections.

This change is BREAKING to connections-enabled construct writers, but
transparent to application builders.

Fixes #579.

- Don't forget to mention that SecurityGroupRef is now abstract
and should be imported.

Can you provide an example here? The description is not clear

private readonly securityGroup: cloudformation.SecurityGroupResource;
private readonly directIngressRules: cloudformation.SecurityGroupResource.IngressProperty[] = [];
private readonly directEgressRules: cloudformation.SecurityGroupResource.EgressProperty[] = [];

constructor(parent: Construct, name: string, props: SecurityGroupProps) {
super(parent, name, { securityGroupId: new Token(() => this.securityGroup.securityGroupId) });
super(parent, name);
this.securityGroupId = new Token(() => this.securityGroup.securityGroupId);
