Inform devs they are not using the latest bundle version

#### What problem would the feature you're requesting solve? Please describe.
We want to let devs know when they are not using the latest bundle version. For supportability and security reasons it is important for customers to be on the latest bundles

#### Describe the solution you'd like
When debugging locally or when executing in Azure I would like a warning message to be written to console/App Insights telling the user they are not using the most recent bundle version with a link to a page that describes how move to the lastest bundle version.

#### Describe alternatives you've considered
Once we have our bundle lifecycle policy approved and documented, we will also be sending email notices to owners of apps that using older bundle versions.

#### Additional context
Here is what I am thinking for the message...
"This app is not using the latest bundle version, for supportability, performance, and security reasons you should update to the latest bundle version x.y.z. [Learn more](https://aka.ms/azfunc-bundle-upgrade)."

Start by identifying how the host determines the bundle version during local debugging and Azure execution, and where console and App Insights messages are emitted. Review the bundle lifecycle policy when available; done means older bundle versions produce a warning with the current version and upgrade link in the requested destinations.
