platform: versioning agents

[psschwei]

As a platform operator, I want to be able to version agents to distinguish between different deploys.

Is this about having multiple instances of agents? Version may be one way they differ, but there could be other aspects around aspects like scalability, performance.

I presume this is an addition to each agent in the catalog having a version (or is it a list of versions, defining what is available?)
