* Protobuf changes to record dependencies for read resources * Add a number of tests for read resources, especially around replacement * Place read resources in the snapshot with "external" bit set Fixes pulumi/pulumi#1521. This commit introduces two new step ops: Read and ReadReplacement. The engine generates Read and ReadReplacement steps when servicing ReadResource RPC calls from the language host. * Fix an omission of OpReadReplace from the step list * Rebase against master * Transition to use V2 Resources by default * Add a semantic "relinquish" operation to the engine If the engine observes that a resource is read and also that the resource exists in the snapshot as a non-external resource, it will not delete the resource if the IDs of the old and new resources match. * Typo fix * CR: add missing comments, DeserializeDeployment -> DeserializeDeploymentV2, ID check
