Log stream for Linux Consumption apps

It seems like we now (at least in the portal) have Log stream supported for Linux Consumption apps.
This means that (at minimum) the command `func azure functionapp logstream --browser` should open this URL:
`/resource/subscriptions//resourceGroups//providers/Microsoft.Web/sites//logStream`
It's currently opening the Live Metrics URL:
`/resource/subscriptions//resourceGroups//providers/microsoft.insights/components/`

We should also investigate if the original command `func azure functionapp logstream ` might also now work.

Start by locating the implementation of `func azure functionapp logstream` and the browser URL construction. Check the current behavior for both the `--browser` and original command forms against the stated `/logStream` URL and determine whether the non-browser command now works. Done means the supported command opens the correct Log Stream destination and the behavior is verified.
