Maven gcloud:run does not use Dockerfile

[waprin]

Trying to run this project:

https://github.com/GoogleCloudPlatform/cloud-bigtable-examples/tree/master/java/managed-vm-gae

Results in maven not picking up Dockerfile (builds wrong image), not reading environment variables, etc.

The dockerfile (for now) has to be located at the root of the built War directory. To achieve this, it has to be in the src area of the Web App, so in https://github.com/GoogleCloudPlatform/cloud-bigtable-examples/tree/master/java/managed-vm-gae/src/main/webapp
