chore(release): 3.0.0 [skip ci]

# [3.0.0](v2.3.1...v3.0.0) (2019-10-27)

* Group CloudFormation resources by AWS service name (#234) ([d0749e6](d0749e6)), closes [#234](#234)

### BREAKING CHANGES

* this change moves all Cloudformation resources to
packages based on the AWS service name. The main motivation for this is
that building goformation on some platforms (Windows) failed due to too
many files in the old cloudformation/resources package. This new package
style has a nice benefit of slightly nicer to use API, but is a breaking
change and will require refactoring existing codebases to update to v3.

Old usage:

```go
import "github.com/awslabs/goformation/v2/cloudformation/resources"

... snip ...

topic := &resources.AWSSNSTopic{}
```

New usage:

```go
import "github.com/awslabs/goformation/v3/cloudformation/sns"

...snip...

topic := &sns.Topic{}
```

Most tests are still failing at this point and need refactoring.

* fix(schema): Tag handling

Fixed tag handling for new grouped resources style (via new tags.Tag
struct).

* fix(schema): SAM specification

SAM Specification now generates nicely with new grouped resources
format. Also all tests are now passing \o/
