Add type codedeploy and codedeploy_deployment_group

[kl4w]

First PR in this repo. Attempts to address #440

Add codedeploy resource types:

• codedeploy
• codedeploy_deployment_group

WIP because I'm currently getting the below failure when generating docs.
I'm slightly confused here as I have the application_name param passed into the get_deployment_group function: https://github.com/k1LoW/awspec/compare/master...kl4w:add-type-codedeploy?expand=1#diff-025a03cb0721734aa0ebab79071e2031R10

I'd appreciate any pointers here if possible.

hi @k1LoW,

I figured out my error due to a "default" not being set: https://github.com/k1LoW/awspec/pull/441/files#diff-726d04686cfa36258f72777465e32f81R19
