aws-autoscaling: support defaultInstanceWarmup

[pb8o]

Describe the feature

Support defaultInstanceWarmup in the AutoScalingGroup L2 construct.

Currently it is not supporter and the docs state:

Not currently supported by CloudFormation.

Which is not the case anymore

Use Case

Right now we have to use the escape hatch.

const cfnASG = asg.node.defaultChild as autoscaling.CfnAutoScalingGroup;
cfnASG.defaultInstanceWarmup = 60;

Proposed Solution

Expose the feature through the L2 Construct.
