v0.1.15 Release

Modular Botorch

• Introduces a new set of abstractions for Botorch models to support customizable, storage-friendly botorch components (e.g. Surrogate, Acquisition).
• See #374 for more information
• A draft tutorial is available at: https://github.com/facebook/Ax/blob/master/tutorials/botorch_modular.ipynb

Logger redesign

• Our logger APIs have been refactored to use a new naming scheme (module name, via getLogger(__name__)) and use a different handler/propagation scheme (1 root handler instead of N+1 child handlers). These changes play nicely with core features of Python's logging API and enable use cases such as #316.

MultiObjective API Improvements

• Introduces some new MOO modeling APIs such as MultiObjectiveTorchModelBridge to support our growing list of MOO features. See 272b6dd
