* Alerting: Tiny refactor on the eval and schedule packages
two very small things:
- We had a constructor on something called a `Context` which is not a `context.Context` so let's just name that constructor `NewContext`
- The user that we use to run query evaluations is the same (with some variation) abstract it to a function so that it can be re-used when necessary.

This commit is one of two commits to make the data frames for all queries and expressions in an alert rule available to the state package for rendering a graph. It renames Result to Condition, and creates an additional field called
Results that is a map of Ref ID to data.Frames.
