custom-resource: support isComplete handler for AwsCustomResource

[maltejk]

Describe the feature

Please add the isCompleteHandler functionality to AwsCustomResource also.

Thank you for your consideration!

As suggested by @hoegertn

Use Case

When I make use of AwsCustomResource to ModifyVpnTunnelOptions, I would not know when the modification completed. As I need to modify both tunnels, adding a dependency would not help. The second AwsCustomResource to run ModifyVpnTunnelOptions would start and fail with an error as the VPN is in state "modifying".

So I would end up creating a CustomResource, so I can make use of the isCompleteHandler.

Generally we'll recommend CustomResource in tis case but we welcome any feature requests. Please help us prioritize by 👍

Having the isComplete handler as part of the AwsCustomResource would help a lot with undifferentiated heavy-lifting as several APIs return without the modification being ready. A polling mech to wait for this to happen would help with all AwsCustomResources that are not read-only.

I will look into drafting a PR for this.
