Generate and paste mode #1
Description
It was cool to have a mode of simply generating and inserting keys in gradle.properties. This is useful when everything is already configured in build.gradle, but you just need to generate the key and paste it into gradle.properties (which is in .gitignore, while build.gradle can not be placed in .gitignore).
And now when I run react-native-android-keystore, you get an error that "Project is already configured for Android release".
