Javascript-SDK - 3.2.0-beta

## [3.2.0-beta] - May 16th, 2019

### Bug Fixes:
- Clear timeout created in `onReady` call for timeout promise as soon as project config manager's ready promise fulfills

### New Features
- Added 60 second timeout for all datafile requests

### Changed
- Updated datafile request polling behavior:
- Start update interval timer immediately after request
- When update interval timer fires during request, wait until request completes, then immediately start next request
- Update TypeScript definitions to account for new methods (`onReady`, `close`) and new properties on object accepted by createInstance (`datafileOptions`, `sdkKey`)
