Azure log exporter is turned off in Hyacinth app

Whilst working on monitoring #151 , found that following line in file app/app.py in hyacinth app was commented out. (This may have been in preparation for the demo). However this causes app to not collect the metric and hence the app monitoring dashboard can not have charts with data.

setup_azurelog_exporter(environment, app.server, instrumentation_key)

To Reproduce
Steps to reproduce the behavior:

1. Go to dev azure environment where Hyacinth is deployed or deploy hyacinth locally.
2. Go to web app/ open it in browser to create some operational logs and metrics.
3. Go to app insights on Azure and notice that the metrics related to requests have not been generated.

Expected behavior
Metrics and logs related to web application activity should be created so that charts with this data can be created in application insights.
