Support for AWS placement group strategies

[pincher95]

Tell us about your request

Support to schedule node based on placement group strategies. As example when you launch a new EC2 instance, the EC2 service attempts to place the instance in such a way that all of your instances are spread out across underlying hardware to minimize correlated failures. You can use placement groups to influence the placement of a group of interdependent instances to meet the needs of your workload.

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?

Need to provision ETCD cluster in the same AZ.

Are you currently working around this issue?

Using ASG with launch template configured to use placement group.

I'm about to close out #3859 do you have a sense of which fields you'd like to see implemented? if so I'd be happy to extend my PR to cover some other scenarios.

@preflightsiren Hey, i would like to see groupId implemented which is placement group id ( E.g pg-xxxxxxxxxxxxxxxxx )
the same way it implemented in LT

Thanks

[preflightsiren]

I've added support in #3859 - once I can get that PR approved and merged, we should be able to get support for placement.groupId in the awsnodetemplate

Thank you

@preflightsiren Is #3859 been promoted or scrapped?

[preflightsiren]

have to change the approach to improve discovery / make configuration more portable between geographies and clusters.
I'm working on it now.
