Joshua Harlow 3a8a78ee64 Use constants for link metadata keys ...

Instead of using strings (which can be easy to
mistype and get wrong), provide a set of constants
that can be used to attach and use these keys in
flows and at compilation.

This also helps make it more clear what the keys
do and where they are used.
