Inconsistent variable usage

There is a var passed around called `filterEntities` that is used to filter what actions are to be deployed because they have changed.

Sometimes it is a Boolean: `true`, sometimes it is `undefined`, and sometimes it is an Object with a property `actions` which is an Array of actionNames ...

`{ filterEntities: { actions: [ 'say-hello' ] } }`

We need to be diligent about the types of objects we use, and they should never change.

Start by locating every use of `filterEntities` in the repository and inspect the callers that pass booleans, `undefined`, or an object with `actions`. Determine the intended single type from those call sites and existing behavior; done means all usages follow that type without changing which actions are deployed.
