I had submitted the pull request #1762
Following the suggestions from dm1try I create a API request generator.
I also added support for all other missing cloudstack API calls.

A have a couple of questions:
1 - In the compute file for cloudstack I see that all the api request files are required.
Wouldn't be better to require just one file where all the api request files are required, this way decoupling the compute file from the api requests?

2 - Another question is regarding the Mock class.
I would like to automate the creation of the Mock class as well as the Real class.
And also create tests for all the API requests. so we can have a solid and robust away to update future api changes.

If you guys like the ideas and want to go ahead  with #1 and #2 I can create the issues so we can keep track of them

I really need to have this pull requests committed since we are planning to put our scripts in production and they depend on this commit, so if there are any changes still pending please let me know and I'll fix them asap.

Thanks 

*what time do you guys usually go to irc?
