Simplify Spring integration

[maciejwalkowiak]

📜 Description

Simplify using Sentry error reporting and Sentry Performance feature in Spring (non-boot) integration. Also, change the sample project for Spring integration into traditional WAR application.

💡 Motivation and Context

Sentry Spring integration was working well with embedded servlet containers scenarios but appeared to be difficult to configure when used in traditional WAR deployment.

Also, fixed: #1187

💚 How did you test it?

Unit & Integration tests.

📝 Checklist

• I reviewed submitted code
• I added tests to verify changes
• All tests passing
• No breaking changes

🔮 Next steps

Since there is a method IHub#getOptions there is a potential to move some bits of sentry-spring to sentry-servlet.
