RFC: use logkitty for `log-android` command

[zamotany]

Describe the Feature

This is a proposal to use 3rd party tool for log-android for prettier messages and more flexible interface: https://github.com/zamotany/logkitty

logkitty currently supports only Android (iOS in the future if requested) with better syntax for common tasks like filtering by tags (logkitty tag myTag otherTag, logkitty tag myTag otherTag -W), filtering by application (logkitty app com.expample.myApp, logkitty app com.expample.myApp -E) and custom patters (logkitty custom *:S ReactNativeJS:D).

Let me know what do you think. Any feedback appreciated.

Possible Implementations

Spawn logkitty process when running react-native log-android.

Given the amount of +1 on @zamotany issue, I think we can say this is a good proposal and should be implemented.

@zamotany, would you be willing to contribute this?
