Combine experiment and gs fields into AnalysisBase

[danielcohenlive]

Summary: AnalysisBase will have optional _experiment and _generation_strategy fields, with getter and setter properties, as well as the standard_generation_strategy prop from Scheduler. Scheduler and AxClient will inherit these from it.

The naming is less than optimal with AnalysisBase holding the experiment and GS.

This is otherwise a no-op change designed to reduce pyre errors.
