Add setShowBadge support for Android channel

[serjek]

Feature Request

Add optional param for channel that will contribute to setShowBadge method on native side. PR is pending.

Why it is needed

Main reason for this is because on some devices badge is incremented automatically and can not be removed even with setApplicationIconBadgeNumber. We wouldn't want to annoy user with badges increasing when it is not really needed so option to disable badge per channel will become handy.

Possible implementation

Simply extend RNPushNotificationHelper.checkOrCreateChannel with extra param and use channel.setShowBadge(value);

Code sample

PushNotification.createChannel({channelId: "no_badge_channel", channelName: "Housekeeping notifications", showBadge: false});
