In management UI have the endpoints /latest and /{environment} for the proxies

Currently when linking to a proxy or shared flow you need to include which revision you want to load. This creates a small issue when linking to proxies from wikis and documentations as they over time point to old revision.

By in the link being able to write /latest or /{environment} instead of /{revision} will make work better with documentation and other tools where links may be placed.

/latest will allways point to the latest revision no matter if it is deployed in an environment or not.
/{environment} will point to the revision that is deployed in the respective environment.

This will save us from the hassle of needing to have outdated links or needing to script to fetch the latest revision.
