    Summary: Windows native build script. This is similar to functionality provided
             by hack\make.sh, but uses native Windows PowerShell semantics. It does
             not support the full set of options provided by the Linux counterpart.
             For example:

             - You can't cross-build Linux docker binaries on Windows
             - Hashes aren't generated on binaries
             - 'Releasing' isn't supported.
             - Integration tests. This is because they currently cannot run inside a container,
               and require significant external setup.

             It does however provided the minimum necessary to support parts of local Windows
             development and Windows to Windows CI.

             Usage Examples (run from repo root):
                "hack\make.ps1 -Client" to build docker.exe client 64-bit binary (remote repo)
                "hack\make.ps1 -TestUnit" to run unit tests
                "hack\make.ps1 -Daemon -TestUnit" to build the daemon and run unit tests
                "hack\make.ps1 -All" to run everything this script knows about that can run in a container
                "hack\make.ps1" to build the daemon binary (same as -Daemon)
                "hack\make.ps1 -Binary" shortcut to -Client and -Daemon

.PARAMETER Client
     Builds the client binaries.

.PARAMETER Daemon
     Builds the daemon binary.

.PARAMETER Binary
     Builds the client and daemon binaries. A convenient shortcut to `make.ps1 -Client -Daemon`.

.PARAMETER Race
     Use -race in go build and go test.

.PARAMETER Noisy
     Use -v in go build.

.PARAMETER ForceBuildAll
     Use -a in go build.

.PARAMETER NoOpt
     Use -gcflags -N -l in go build to disable optimisation (can aide debugging).

.PARAMETER CommitSuffix
     Adds a custom string to be appended to the commit ID (spaces are stripped).

.PARAMETER DCO
     Runs the DCO (Developer Certificate Of Origin) test (must be run outside a container).

.PARAMETER PkgImports
     Runs the pkg\ directory imports test (must be run outside a container).

.PARAMETER GoFormat
     Runs the Go formatting test (must be run outside a container).

.PARAMETER TestUnit
     Runs unit tests.

.PARAMETER TestIntegration
     Runs integration tests.

.PARAMETER TestIntegrationCli
     Runs integration-cli tests.

.PARAMETER All
     Runs everything this script knows about that can run in a container.


TODO
- Unify the head commit
- Add golint and other checks (swagger maybe?)
