Upgrade dependencies, dropping support for Go versions < 1.17

Recent versions of golang.org/x/sys use unsafe.Slice, which was
introduced in Go 1.17. This package maintained compatibility with
Go 1.16 because for a long time that was the latest version of Go
that App Engine supported.

App Engine now supports Go 1.19 so we no longer need to keep from
upgrading this package. If you're still using the go116 runtime then
don't upgrade this package past v1.0.1.

Get Cloud Run env vars before calling metadata service for project ID

Checking the env vars is faster than calling the metadata service, so
hopefully this will bail out faster if we're not on Cloud Run.

Even if the call to the metadata service takes a long time it will only
happen on the first request to trigger it.

Add test for handler wrapping
