otopi Machine Dialog Parser for python

This module allows you automate installation process based on
[otopi](https://github.com/oVirt/otopi) installator.

# Requirements

```
otopi
```

# Usage

1. Set otopi environment to enable machine dialect

DIALOG/dialect=str:machine

2. Spawn desired installer and pass stdin and stdout to parser
3. Process all otopi events in the loop


## Example for oVirt Hosted Engine

```python
import subprocess
import otopimdp as mdp

# 1. Set machine dialog option
with open("/etc/ovirt-hosted-engine-setup.env.d/mycustom.env") as fd:
fd.write(
'export environment="${environment} DIALOG/dialect=str:machine"\n'
)

# 2. Spawn installer
installer = subprocess.Popen(["hosted-engine", "--deploy"])
parser = mdp.MachineDialogParser(
input_=installer.stdout, output=installer.stdin
)

# 3. Process events
while True:
event = parser.next_event()
if event is None:
continue
event_type = event[mdp.TYPE_KEY]
if event_type == mdp.TERMINATE_EVENT:
break

event_name = event[mdp.ATTRIBUTES_KEY]['name']
if event_name == "OVEHOSTED_HOST_ID":
event[mdp.REPLY_KEY] = "1"
....
parser.send_response(event)
```
