Ramsés Morales a7a48168a0 Add golangci-lint config file and make target.
Here we add file `.golangci.yaml`, to have a common configuration for
static analysis. If you use the following IDEs/editors, they will read
the file:

- `vim` with vim-go.
- VSCode.

The initial configuration file is based on Kubernetes' HEAD. We removed
a custom kubernetes-linter for custom kubernetes-logging. We also
changed to Golang version 1.17 (etcd's current target Golang version)
from 1.18.

Also, we added a new target to `Makefile`: `lint`. NOTE that auto-fixing
should be part of a later commit, once we are all happy with how the
configuration file is working for us.

As expected, this change fixes two issues found by this `.golangci.yaml`
in file `contrib/lock/client/client.go`:

- Dead code, removed.
- Innefective assignment, removed.

Finally, we are updating `CONTRIBUTING.md` to mention `golangci-lint`.

We will add a GitHub-action to run `golangci-lint` in a future change.

Local testing done:

- `make build`.
- `make test`.

Both are happy.

This is the initial step to fix
https://github.com/etcd-io/etcd/issues/14164.
