Introduced a JSON schema of a leapp report

Generated by https://jsonschema.net and adjusted manually.

The patch contains 2 schema files:
- 1.0.0 that matches the version that foreman_leapp relies on
- 1.1.0 that has the stable report key.

Basic unit test coverage is presented in test_reporting.py - the
sample leapp-report.json from vagrant box is checked against json
schema v 1.0.0 and 1.1.0.
