Support !include and !import constructors in awx import -f yaml command

ISSUE TYPE

• Feature Idea

SUMMARY

Support !import and !include with awx import -f yaml command. This is useful when working with a large number of AWX resources. This allows breaking config into smaller files, and having a top-level file like this:

# resources.yaml
projects:
- !include projects/project1.yaml
- !include projects/project2.yaml
job_templates:
- !include jobs/job1.yaml

# ....

Which allows managing resources in individual files (e.g. using a friendly directory structure), and still being able to import with awx import -f yaml < resources.yaml.

SUGGESTED IMPLEMENTATION

Use awxkit.yaml_file.Loader instead of yaml.safe_load in https://github.com/ansible/awx/blob/devel/awxkit/awxkit/cli/resource.py#L143
