As of this commit this provider has only logical resources that allow
the creation of private keys, self-signed certs and certificate requests.
These can be useful when creating other resources that use TLS
certificates, such as AWS Elastic Load Balancers.
Later it could grow to include support for real certificate provision from
CAs using the LetsEncrypt ACME protocol, once it is stable.
A "Layer" is a particular service that forms part of the infrastructure for
a set of applications. Some layers are application servers and others are
pure infrastructure, like MySQL servers or load balancers.
Although the AWS API only has one type called "Layer", it actually has
a number of different "soft" types that each have slightly different
validation rules and extra properties that are packed into the Attributes
map.
To make the validation rule differences explicit in Terraform, and to make
the Terraform structure more closely resemble the OpsWorks UI than its
API, we use a separate resource type per layer type, with the common code
factored out into a shared struct type.
"Stack" is the root concept in OpsWorks, and acts as a container for a number
of different "layers" that each provide some service for an application.
A stack isn't very interesting on its own, but it needs to be created before
any layers can be created.
Here we add an OpsWorks client instance to the central client bundle and
establish a new documentation section, both of which will be fleshed out in
subsequent commits that add some OpsWorks resources.
AWS provides three different ways to create AMIs that each have different
inputs, but once they are complete the same management operations apply.
Thus these three resources each have a different "Create" implementation
but then share the same "Read", "Update" and "Delete" implementations.
Common metadata state is now stored
Optimistic locking support added to common_metadata
Revisions to keys in project metadata are now reflected in the project state
Wrote tests for project metadata (all pass)
Relaxed test conditions to work on projects with extra keys
Added documentation for project metadata
