Support individual packaging, or clearly reject if there's no intention to support it

[medikoo]

Currently if serverless.yml is set with package.individually, deployment crahes with error as such:

 Error: Function app zip file 'XXX' does not exist

If for some reason there's no intention to support individual per-function packaging, then I believe it should be reported with clear message as:

Azure plugin does not support `pakcage.individually` option.

Just to be clear, the setting is configured as:

service: myService

package:
    individually: true
...

Correct?

Yes, it's about: https://serverless.com/framework/docs/providers/aws/guide/packaging/#individual-function-packages

While Serverless documents it in context of AWS, the setting is in global context, and also Azure relies on same packaging functions which react to those setting.
