bastion host machine size

[rosera]

Using this demo via the Qwiklabs environment (GSP482 - Securing Applications on Kubernetes Engine - Three Examples) and the bastion host is timing out when provisioned from Terraform.

The issue appears to be the following definition (variables.tf):
variable "bastion_machine_type" {
description = "The instance size to use for your bastion instance."
type = string
default = "f1-micro"
}

Amending the default instance type to a more powerful instance ensure the host is provisioned correctly.

I have patched the lab to change the bastion machine to n1-standard-1 to fix the timeout. Not sure if I should raise a PR to amend this in the repo as well?
