Extend asg module to enable or disable delicensing FW by Lambda after scale in

[sebastianczech]

Is your feature request related to a problem?

Few weeks ago it was decided not to include delicense code in asg module, but now when we are adding this behaviour for GCP in PR 191, then similar feature should be available in AWS.

Describe the solution you'd like

• add option for asg module to enable or disable delicense FW by Lambda
• add Python function to do delicense

Describe alternatives you've considered.

Plugin sw_fw_license enable delicensing after N hours, where 1 <= N <= 24 hours. For some use case event based approach (just after scale in) is preferred one (instead of waiting at least 1 hour).

Additional context

After delivering PR for that issue customer will have a choice:

• use event based approach and delicense just after scale in
• do not use additional Python code in Lambda and wait at least 1 hour to delicense removed FW
