introduce podman machine

Browse Source 
podman machine allows podman to create, manage, and interact with a vm
running some form of linux (default is fcos).  podman is then configured
to be able to interact with the vm automatically.

while this is usable on linux, the real push is to get this working on
both current apple architectures in macos.

Ashley Cui contributed to this PR and was a great help.

QMP
===
Package `qmp` enables interaction with QEMU instances via the QEMU Machine Protocol (QMP).
## Available Drivers
### Libvirt
If your environment is managed by Libvirt, QMP interaction must be proxied through the Libvirt daemon. This can be be done through two available drivers:
#### RPC
The RPC driver provides a pure Go implementation of Libvirt's RPC protocol.
```go
//conn, err := net.DialTimeout("unix", "/var/run/libvirt/libvirt-sock", 2*time.Second)
conn, err := net.DialTimeout("tcp", "192.168.1.1:16509", 2*time.Second)
monitor := libvirtrpc.New("stage-lb-1", conn)
```
#### virsh
A connection to the monitor socket is provided by proxing requests through the `virsh` executable.
```go
monitor, err := qmp.NewLibvirtMonitor("qemu:///system", "stage-lb-1")
```
### Socket
If your QEMU instances are not managed by libvirt, direct communication over its UNIX socket is available.
```go
monitor, err := qmp.NewSocketMonitor("unix", "/var/lib/qemu/example.monitor", 2*time.Second)
```
## Examples
Using the above to establish a new `qmp.Monitor`, the following examples provide a brief overview of QMP usage.
_error checking omitted for the sake of brevity._
### Command Execution
```go
type StatusResult struct {
ID string `json:"id"`
Return struct {
Running bool `json:"running"`
Singlestep bool `json:"singlestep"`
Status string `json:"status"`
} `json:"return"`
}
monitor.Connect()
defer monitor.Disconnect()
cmd := []byte(`{ "execute": "query-status" }`)
raw, _ := monitor.Run(cmd)
var result StatusResult
json.Unmarshal(raw, &result)
fmt.Println(result.Return.Status)
```
```
running
```
### Event Monitor
```go
monitor.Connect()
defer monitor.Disconnect()
stream, _ := monitor.Events()
for e := range stream {
log.Printf("EVENT: %s", e.Event)
}
```
```
$ virsh reboot example
Domain example is being rebooted
```
```
EVENT: POWERDOWN
EVENT: SHUTDOWN
EVENT: STOP
EVENT: RESET
EVENT: RESUME
EVENT: RESET
...
```
