SoftwareDeployments and StructuredDeployments resource type names are confusing

[Thomas Spatzier]

We currently have type OS::Heat::SoftwareDeployment and OS::Heat::StructureDeployment and plural versions of it for deploying to groups of servers (OS::Heat::SoftwareDeployments and OS::Heat::StructuredDeployments).
The current naming for the groups ones is confusing, since in documents or communicating with other people it is never clear if one is talking about the plural version of the 'normal' resources or the group resources.

Proposal is to rename the 's' versions to
OS::Heat::SoftwareDeploymentGroup and
OS::Heat::StructuredDeploymentGroup

When doing this change, we can keep the resource mappings for the old 's' names so existing templates won't break.

    Rename OS::Heat::SoftwareDeployments

    Rename the SoftwareDeployments resource to SoftwareDeploymentGroup to
    avoid awkward situations when talking about the plural form of the
    SoftwareDeployment resource. This has been agreed at the Vancouver
    summit.

    The existing 'SoftwareDeployments' resource is kept for backwards
    compatibility, but with a deprecated status and corresponding
    deprecation message.
