This commit creates a create_cluster directory to collect
all Vue applications related to creating kubernetes applications
using gitlab.

It also moves the gke_cluster_dropdowns collection of apps to
the create_cluster directory. gke_cluster_dropdowns contains
dropdown components used to select configuration options to
create a Kubernetes cluster in Google Cloud.

each suite needs its own instance of the store, but the state has to be returned via a factory otherwise the suites all share the same reference to one state object
