Open Stack

Hi,
I am trying to set up a CI environment, and get some troubles. I follow the guild 'https://docs.openstack.org/infra/openstackci/third_party_ci.html', and in the end of step 'start nodepool' I get a HTTP Error 405, following is the error log in /var/log/nodepool/nodepool.log:
```

  File "/usr/lib/python2.7/urllib2.py", line 410, in open

HTTPError: HTTP Error 405: Method Not Allowed

```
I checked the code at the end of  file '/usr/local/lib/python2.7/dist-packages/nodepool/myjenkins.py', and found that the default http method is 'GET',  so I change the method to 'POST'，and solved the problem.
The changed code is following, where the commented code is the original code, and the rest are what I added.:
```
        req = urlrequest.Request(
             self.server + CREATE_NODE % urlparse.urlencode(params))
        method = "POST"
        req.get_method = lambda: method
        self.jenkins_open(req)
        #self.jenkins_open(urlrequest.Request(
        #    self.server + CREATE_NODE % urlparse.urlencode(params)))

```
So, my question is: Are there any config file that I can set the HTTP method to 'POST', or is there a bug needed to be fixed? I need your help, thanks!
