Create migration issue from snippet of code

Rule construction could start with marking/selecting code that needs to be migrated or changed, then have the tooling create an empty rule that points to this piece of code (perhaps intelligently generate a <when> clause that best suits the selected code and context), that developer could then add some comments and share the rule with the team. Someone else knowledgeable on rule construction could then finish the implementation.

Built in Intelligence: Detect what type of file, as well as what type of content is selected. For example, if "implements SomeInterface" is selected, we could pick a template with a when clause matches an interface.
