* Add ability to specify Terraform Cloud Project in cloud block
Adds project configuration to the workspaces section of the cloud block.
Also configurable via the `TF_CLOUD_PROJECT` environment variable.
When a project is configured, the following behaviors will occur:
- `terraform init` with workspaces.name configured will create the workspace in the given project
- `terraform workspace new <name>` with workspaces.tags configured will create workspaces in the given project
- `terraform workspace list` will list workspaces only from the given project
The following behaviors are NOT affected by project configuration
- `terraform workspace delete <name>` does not validate the workspace's inclusion in the given project
- When initializing a workspace that already exists in Terraform Cloud, the workspace's parent project is NOT validated against the given project
Adds tests for cloud block configuration of project
Update changelog
* Update cloud block docs
* Fix typos and changelog entry
* Add speculative project lookup early in the cloud initialize process to capture inability to find a configured project
* Add project config for alias test
