Contributed code removed in v5

[System-Glitch]

Some code from contributors is removed in v5. I would like to notice the owners and explain the reasons behind the removal. I sincerely appreciate the work everyone of you submitted!

@agbaraka

• utils.Map: the syntax map[string]any is short enough to not be annoying to write. So I decided to make the package lighter and remove it. If you still want to use it, this is still a simple type to implement inside your projects.
• ratelimit package: This implementation couldn't be used in a realistic production environment and didn't cover critical aspects of a real application.
  • Slow because of too many mutex locks
  • Memory hungry
  • Completely resets if the application restarts (which is very common when deployed on a cloud service)
  • Not distributed (meaning it is impossible to use when working with multiple instances and load balancing)
  • Weak policy (simple time window) whereas more efficient policies such as the leaky bucket could be used
  • Outdated because based on an older IETF draft
  • It is recommended to use better alternatives such as redis_rate.

@imuni4fun

• TestSuite has been entirely removed, including your change on interface compatibility. The testing utilities are now located in a package util/testutil. This package is agnostic, meaning it doesn't depend on testify anymore.

Thank you again for your work, and I hope you enjoy using the framework! Your contributions will always be welcome.
