Summary:
**Motivation**
Ability to customize slider colors is desirable to match the brand. Currently iOS allows using images for slider parts, but android doesn't have any customization options. This PR adds support for customizing `thumbTintColor`, `trackTintColor` and `progressTintColor`.
**Test plan (required)**
Run UIExplorer example with the changes and verify everything works fine.
