Bevy: InputMap Plugin

[PradeepKumarRajamanickam]

It would be nice to have an InputMap system like in godot or unreal's ActionMappings. It will convert user input from different input hardware into game specific actions.

eg,
Keyboard "Space" or Joystick "A" can be mapped "Jump" Action.

This allows game code to not be tightly coupled with a particular key event. It also makes key rebinding possible if we add support for storing keybindings in an external json file (or something similar).

Yeah I think this is a must-have feature for serious games. People can currently build their own versions of this on top of the existing input events, but it makes sense to build something standard that everyone can use.
