Extend "S3 buckets with SSE-KMS" documentation

[drernie]

Description

Add new sections technical-reference.md about explicit Allow permissions required by KMS

In order for Quilt to access and index buckets encrypted with SSE-KMS, you must do three things:

1. Add KMS Key Usage to Quilt Permission Boundary
2. Add Quilt Principals to KMS Key Policy [this was the old section]
3. Add KMS Key Access to Quilt Role
