add acm certificate hook

[ITProKyle]

Summary

Create & destroy a certificate in ACM with DNS validation when the domain is hosted in Route 53 in the same account the certificate is being created.

Why This Is Needed

When creating a certification in ACM with DNS validation with CloudFormation, there is a manual step involved to get a record set of the stack's events and add it to Route 53. This automates the process.

What Changed

Added

• base hook class
• support for handle_hooks to use functions or classes
  • classes must have a method for each stage they can be used with (e.g. pre_deploy, post_destroy)
• altered classes for use in a hooks without introducing cyclic imports or requiring a full "create a plan, run plan, load blueprint from file, render it, etc" workflow when used in a hook
  • allows the hook to use existing logic from elsewhere
• add hook for creating a certificate in acm using CloudFormation and validating it with Route 53
