Expected behavior

Cloud function should process more than 1 min and less than 9min.
The main root cause is it doesn't allow us to set timeout option under httpCallable in AngularFire as mentioned here

Actual behavior

Cloud function run for 500 seconds if usuing Firebase official SDK
Cloud function run at most 60 seconds if using AngularFire package
