IBinder Dependency Injection into class constructor

#### What problem would the feature you're requesting solve? Please describe.
I have a number of common/shared features that functions utilise, so have created a abstract class named BaseFunction; and need the ExecutionContext and IBinder

#### Describe the solution you'd like
I would like for these o be injected so common functions may consume these with out the executing trigger having to be concerned about these.

#### Describe alternatives you've considered
#### Additional context

The issue names an abstract BaseFunction class and the ExecutionContext and IBinder dependencies, but no files, tests, or entry points. Start by locating the constructor and dependency-injection paths for these types in the repository. Done should be defined as a supported way for shared functions to consume both dependencies without each trigger supplying them.
