all: release v0.37.4

This comes with a re-built go.sum generated with `go mod tidy`. It was
not possible to build the go.sum previously because we were depending on
future versions of libraries.

This commit will be tagged v0.37.4.

mod: switch to non-alpha future versions of opencensus, google.golang…

….org/api

The experiment proved mostly successful: we are able to remove
github.com/golang/lint from our mod graph, and we are able to
GO111MODULE=on go get -u ./... on this repo. However we're not able to do the
latter in opencensus or google.golang.org/api for some reason (despite the
mod graph having excised github.com/golang/lint). Filing an issue in golang/go
for the remaining weirdness, for but now this is still forward progress.

This will be tagged 0.37.3.
