Manage .golangci.yml

[blampe]

Currently, it's up to each provider to decide how to lint itself -- or whether we apply linting at all! This leads to inconsistency across projects.

We should agree on some baseline rules for linting and then deploy those with ci-mgmt to provider repos.

This appears this is already generated via ci-mgmt:

• https://github.com/pulumi/ci-mgmt/blob/master/provider-ci/internal/pkg/templates/provider/.golangci.yml

This file was originally added in 2020.

Happy to close this issue or is this relating to something else?
