Major version bump to v2.x

I would love for github-api v2.x to be a larger change that has major new features.

However, the most pressing need is clearing technical debt for better stability and ease of adding new features. These changes break binary compatibility requiring a major version bump.

v2.0 includes:

• Drop support for Java 8
• Remove functional dependencies on HttpURLConnection
• Remove most deprecated classes and methods
• Remove all "bridge methods"
• Test clean up
• Site generation updates
• First GraphQL endpoint
