Implement Java library for BigBlueButton #3

Description
Create an official Java library for BigBlueButton.

Motivations
Currently official BigBlueButton holds the official PHP library https://github.com/bigbluebutton/bigbluebutton-api-php then Mconf maintains the Ruby library https://github.com/mconf/bigbluebutton-api-ruby

Gathering everyone around a community-maintained java library is very useful as example for implementing, JVM server side applications, CLI tools, implementing Selenium tests with Java and extending BigBlueButton server features for custom-built BigBlueButton platforms.

Technical Requirements

• Support JVM 11+
• Support BigBlueButton API 2.6+

Functional Requirements

• Easy integration: The library should be easy to integrate with other applications and provide clear documentation and examples to help developers get started quickly.
• Robust error handling: The library should have robust error handling to handle BigBlueButton API specific error scenarios that can occur during API calls and prevent misuses or wrong assumptions of the API understanding.
• Flexibility: The library should be flexible and provide options to configure the library's behavior, such using environment variables, configuring hash algorithm.
• Performance: The library should be optimized for performance and have minimal overhead by using third party libraries as less as possible.
• Testing and coverage: The library should have unit tests implemented for almost every line. A 80%+ of code coverage is advised to comply to quality standards.
