[ansible] Add apply_win_os_update role and playbook.

This playbook runs the Windows 10 Update Assistant on Windows machines, which updates the operating system to the latest version.

I ran this playbook on the following machines:

- skia-e-win-[260-267]
- skia-e-win-[367-368]
- skia-e-win-[380-388]

The playbook finished successfully on all machines, and now our entire Windows fleet is now running Windows-10-19044.2006.

The necessary steps for future Windows updates are as follows:

1. Go to https://www.microsoft.com/en-us/software-download/windows10 from a Windows machine, and download the latest Windows 10 Update Assistant binary.
2. Upload said binary to gs://skia-buildbots/skolo/win/win_package_src.
3. Update the variables in //skolo/ansible/switchboard/roles/apply_win_os_update/vars/main.yml with the new Windows version and Windows 10 Update Assistant binary.
4. Run this playbook on all relevant machines.

Skia-Buildbot Repository

This repo contains infrastructure code for Skia.

Getting the Source Code

The main source code repository is a Git repository hosted at https://skia.googlesource.com/buildbot.git. It is possible to check out this repository directly with git clone or via go get.

Using git clone allows you to work in whatever directory you want. You will still need to set GOPATH in order to build some apps (recommended to put this in a cache dir). E.g.:

$ cd ${WORKDIR}
$ git clone https://skia.googlesource.com/buildbot.git
$ export GOPATH=${HOME}/.cache/gopath/$(basename ${WORKDIR})
$ mkdir $GOPATH
$ cd buildbot

Using go get will fetch the repository into your GOPATH directory along with all the Go dependencies. You will need to set GOPATH and GO111MODULE=on. E.g.:

$ export GOPATH=${WORKDIR}
$ export GO111MODULE=on
$ go get -u -t go.skia.org/infra/...
$ cd ${GOPATH}/src/go.skia.org/infra/

Note: go.skia.org is a custom import path and will only work if used like the examples here.

Install Node.js (not as root) and add the bin dir to your path. Optionally run npm install npm -g, as suggested by the npm getting started doc.

Install other dependencies:

$ sudo apt-get install \
    jq \
    python-django
$ go get -u \
    github.com/kisielk/errcheck \
    golang.org/x/tools/cmd/goimports \
    go.chromium.org/luci/client/cmd/isolate \
    go get github.com/mikefarah/yq/v4

Build ~everything:

$ make all

Generated Code

Some code is generated using go generate with external binaries. First, install the version of protoc referenced in the asset creation script and ensure it is on your PATH before other versions of protoc.

Install the necessary go packages:

$ go get -u \
  github.com/golang/protobuf/protoc-gen-go \
  golang.org/x/tools/cmd/stringer \
  google.golang.org/grpc \

To generate code run in this directory:

$ go generate ./...

Running unit tests

Install Cloud SDK.

Use this command to run the presubmit tests:

$ ./run_unittests --small
