Add partial deployments to pulumi

[limwa]

In pulumi, partial deployments are useful to lower the amount of resources being used by the cluster in development. Partial deployments allow only the resources needed to deploy a given resource to be updated.

This can be done using the --dry-run and --json flags in the pulumi up command to get the dependency graph of the resources and then, with some custom code, get the URNs of the resources that the target resource depends on and update them using the --target flag.
