Add AWSClusterTemplate type

[ykakarap]

/kind feature

Describe the solution you'd like:
Add a new CRD named AWSClusterTemplate. This is needed for ClusterClass.
In the short term this type will not be used outside of ClusterClass.

FYI When implementing this please make sure that the template type applies the same defaulting & validation rules of the actual type, otherwise this could trigger continuous reconcile loop down the path when comparing the desired state (the AWSClusterTemplate object) with the actual state (the instance of AWSCluster generated from the template)

You are completely correct.
I thought I assigned the issue when I created it.
I should have double checked. My bad. 😅
