Add api-versions support to template-all script

Motivation

The template-all script does not allow the user to specify api-versions that flow into the package template commands. This prevents certain templates from being rendered as they're conditionally rendered based on API availability.

Acceptance Criteria

• The script must define a solid set of default api versions
• The script must flow any api versions provided to the script by the --api-versions or -a flags into the package template commands
