Initial TorchX Component for Hyper-parameter tuning (#510)
UX:
Exposes
grid_search
andbayesian
candidate selection strategies and requires input to define search space, eg:Further ideas: next things that can be added are constraints on output and constraints on the input pairs/combinations (depending whether underlining library supports that)

Implementation:
Uses AX Client library (hence limitation on sequential trails). We can migrate to AX's TorchXRunner+AX Scheduler, however this will require get UX correct to define evaluation and metric output processing.
Test plan:
Running locally:
