[artyorsh]

Please read and mark the following check list before creating a pull request:

• I read and followed the CONTRIBUTING.md guide.
• I read and followed the New Feature Checklist guide.

Short description of what this resolves:

• Implements Popover and Tooltip components

NOTES

During ui test implementation discovered that there is no way to test react element measurements.
So currently there are no ui tests, but I've covered models.

Used force-push to remove commits with bug fixes in module resolution for ApplicationProvider which are implemented in #264
