Make managing CloudFormation stacks a little friendlier.

Still very much a work in progress

$ pip install cfnbot

# First, write a specfile. See `example_specfile.yml` for more info.
$ cfnbot deploy [--debug] /path/to/specfile.yml [--stackset <name>]
$ cfnbot delete [--debug] /path/to/specfile.yml [--stackset <name>]

One top key only, which can't be "Default" or "Stacks". Must contain a TemplatePath.

---
SomeAppBucket:
    TemplatePath: 'bucket.yml'
    Parameters: [...]

One top key only, "Stacks", and its value must be a list. For example:

---
Stacks:
    - SomeAppBucketRole:
        TemplatePath: cfn/iam_role.yml
        Parameters: [...]
    - SomeAppBucket:
        TemplatePath: cfn/s3bucket_with_roles.yml
        StackName: SomeAppBucket
        Parameters: [...]

ALL THE THINGS. Need a Default in there somewhere, and it needs a Stacks list.

---
Dev:
  StackNamePrefix: Dev
  CredentialProfile: default
  Stacks:
    - SomeAppBucketLambdaRole
        TemplatePath: cfn/iam_role_dev.yml
Default:
    Stacks:
        - SomeAppBucketRole:
            TemplatePath: cfn/iam_role.yml
            Parameters: [...]
        - SomeAppBucket:
            TemplatePath: cfn/s3bucket_with_roles.yml
            StackName: SomeAppBucket
            Parameters: [...]
