TangoGQL Features Toggle

TangoGQL has a function called features toggle capable of controling some features such as pub/sub. There is a file inside tangogql/ called tangogql.ini, the file looks like this:

# this configuration file is used to hold details of which features
# currently enabled in TangoGQL ( True = enabled False = disabled)

[feature_flags]
# Publish Subscribe is enable
publish_subscribe = True

Changing the publish_subscribe = True will enabled pub/sub on TangoGQL, in this case, TangoGQL will try to Subscribe to changeEvents on the device, if it fails it tries PeriodicEvents, and if that fails it falls back to polling
