[monkey-runner] Install MonkeyTrap app automatically

[xrigau]

It'd be nice if the plugin did this for you. Perhaps the apk should be bundled with the plugin and then before running the monkey tasks, if the app is not installed (or if it's an older version), it would install it automagically ✨ .

For this, we need versioning 😄:

or if it's an older version

I agree that it can be installed automatically. Not have to be bundled at all, we can download in a gradle task.

yeah downloaded and cached for future use 👍
