#10339 introduces an Agent API version

Update the AgentVersion to include 3 states as follows, taking the first condition that matches.

1. If the Agent's API Version is 1 or more major versions behind the Server's latest Agent API Version, display Deprecated
2. If the Agent's Product Version is behind the Server's Product Version, display Outdated
3. Otherwise, display Updated

Deprecated version can share more or less the same tooltip as Outdated does today

c.f. "Updated" below
