Change timeout for Azure builder

[Prashanth Venugopal]

I am trying to use azure builder with shared gallery replication (packer version 1.4.2). The builder seems to timeout if I put in too many replication regions. Looks like 15 mins is the default value.

The config below seems to work, but when I add a few more region, the builder fails with the error below. Is there a way I could pass in a user-defined timeout for the azure builder ? 

Error -:

2019/07/12 22:39:23 ui error: ==> azure: Future#WaitForCompletion: context has been cancelled: StatusCode=200 -- Original Error: context deadline exceede

Config -:

Hi, I'm having the same issue but I'm not finding anything on this subject, do you have by any chance found a solution to increase the default value of the timeout?
