adding WebHost console logs when developing

[brettsam]

During development, we get console logs from the ScriptHost, but nothing from the WebHost. With this, we'll see similar logs to those we see in Kusto when AZURE_FUNCTIONS_ENVIRONMENT is Development.

FNH currently use a workaround to strip out the language worker console log prefix , so that the logs appear in the terminal during local development. With this change, I can remove that workaround now.
