igwejk/even up the defaults across ghas features (#142)

* Remove .vscode/launch.json in favour of npm scripts

* Implement validation of feature enablement config

* Separately implement filter and mapping predicates

The predicates are for filtering or mapping repository nodes.

* Ensure paginateQuery fulfills only its concern

paginateQuery should focus on the concern of returning repositories, and should not modify query results.

* Consider repository characteristics for feature

Individual repository characteristics should determin how features are enabled.

* Control calls to predicates

Otherwise they are passed wrong parameter values that stops good defaults from being used.

* Skip attempting to enable GHAS for public repos

Because it can't be disabled anyway.

* Add package-lock.json
