Is your feature request related to a problem? Please describe.

When a new template version is available, apex cli should produce a confirmation dialog when executed.

Propose a solution

when a user runs apex new, it should check if the template has a new version available and if so, should alert the user and prompt if they really want to continue. It should break the workflow unless a flag is sent to not check for updates.
