Changes

• Adds an experimental --target flag to topo configure and topo clone. This parses a new bit of metadata attached to x-topo.parameters.* that can be used to bind a parameter value to a target fact (as introduced in refactor: introduce concept of target facts + add target memory facts #557). For example:

x-topo:
  parameters:
    TARGET_MEMORY_KB:
      description: Physical memory on the deployment target
      source:
        provider: topo.memory
        group: system-memory
        fact: memory.total

• This allows for some basic level of target-aware configuration of a project without introducing a fragile name-based parameter contract.
• Warns if you configure a project that attempts to bind to target facts and you don't have a target set. Instead you'll just be asked for a value in the interactive resolver.
• No docs or schema changes while this remains experimental!
