flavor support about buildkonfig

[yshrsmz]

passing value via command line will work, but I'm not sure how I can do that in Android Studio/IntelliJ IDEA

$ ./gradlew -Pbuildkonfig.flavor=dev build

[yshrsmz]

• Setting default value in gradle.properties
• Edit gradle.properties while development
• overwrite by passing -P in CI

This should work

NamedDomainObjectContainer is Set, so duplicated name is not allowed.

buildkonfig {
  defaultConfigs("dev") {}
  defaultConfigs("release") {}

  // void targetConfigs(String flavor, Closure closure)
  targetConfigs("dev") {
    android {
    }
    ios {
    }
  }
  targetConfigs("release") {
    android {
    }
    ios {
    }
  }
}

Also, defaultConfigs should be configurable per flavor
