chore: add linter workflow, commit templates and update workspaces (#9)

* cache node_modules and add linting to pr workflow
* commit templates (we should have templates as a shared resource)
* updates to workspaces and lerna
* get everything to finally build

COMMENTING OUT TESTS IN `cdk-change-analyzer-models` see #10
