The internal GCP package used `pkg.go.dev/google.golang.org/api` [1] to interact with Compute Engine API. Modify the package to use the new and idiomatic `pkg.go.dev/cloud.google.com/go` [2] library for interacting with the Compute Engine API. The new library have been already used to interact with the Cloudbuild and Storage APIs. The new library was not used for Compute Engine since the beginning, because at that time, it didn't support Compute Engine. Update go.mod and vendored packages.

xxhash
xxhash is a Go implementation of the 64-bit xxHash algorithm, XXH64. This is a high-quality hashing algorithm that is much faster than anything in the Go standard library.
The API is very small, taking its cue from the other hashing packages in the standard library:
$ go doc github.com/cespare/xxhash !
package xxhash // import "github.com/cespare/xxhash"
Package xxhash implements the 64-bit variant of xxHash (XXH64) as described
at http://cyan4973.github.io/xxHash/.
func New() hash.Hash64
func Sum64(b []byte) uint64
func Sum64String(s string) uint64
This implementation provides a fast pure-Go implementation and an even faster assembly implementation for amd64.
Benchmarks
Here are some quick benchmarks comparing the pure-Go and assembly implementations of Sum64 against another popular Go XXH64 implementation, github.com/OneOfOne/xxhash:
