Remove default node pools and manage them explicitly

[pratikmallya]

The default node pools cause trouble with managing the cluster. It seems like a better architecture to manage the node pools explicitly. Does it make sense to use the remove_default_node_pool parameter for the google_container_cluster and add just manage the node pools explicitly?

We definitely encourage explicitly managing the node pools, as shown in the examples: https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/tree/master/examples/node_pool

Regarding the remove_default_node_pool parameter, I believe we ran into some trouble with bootstrapping using it. @ryanckoch can share more. The approach we have today is, I believe, to create a default node pool with 0 nodes.

Oh, would love to hear about what the issues were with using that parameter @ryanckoch :)

I would love to see this fixed too!

I'd also like to help get this fixed - what was the issue with the remove_default_node_pool parameter? @ryanckoch

[morgante]

@ryanckoch Can you chime in here?
