Switch from cglib to byte-buddy

Description

After launching the first instance of the Appium driver, I get the following warning:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by net.sf.cglib.core.ReflectUtils$1 (file:/Users/aaron.schwieterman/.m2/repository/cglib/cglib/3.3.0/cglib-3.3.0.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)
WARNING: Please consider reporting this to the maintainers of net.sf.cglib.core.ReflectUtils$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

It seems like the best solution to avoid this warning would be to replace cglib with byte-buddy based on this issue.

Environment

• Java client build version or git revision if you use some snapshot: v7.5.0
• Java version: v15.0.2
• Appium server version or git revision if you use some snapshot: v1.20.2
• Desktop OS/version used to run Appium if necessary: macOS Big Sur v11.2.3
• Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe: Appium.app v1.20.2
• Mobile platform/version under test: Android v11
• Real device or emulator/simulator: Real device

Code To Reproduce Issue

driver = new AndroidDriver<>(new URL(url), desiredCapabilities);

Start by locating the project's dependency declarations and every use of cglib, then reproduce the warning with Java 15 and the AndroidDriver entry point shown in the issue. The change is complete when cglib is replaced with byte-buddy, the driver starts without the illegal reflective access warning, and the existing test suite passes.
