Show in foreground feature for android

[aurimasc]

A new feature proposed by innogames: ability to make notification only show up when app is in background (iOS already had this feature, so this brings more parity).

After this change:

• no change to default behavior, notifications work the way they used to if the new property is not touched (show in foreground)
• if ShowInForeground is set to false notification will only be shown when app is in background, but will not be shown when app is in foreground
• application does get notified about notification delivery regardless of property value, that is if ShowInForeground is false, notification is delivered to app silently, no user visible notification is shown on device

Test coverage:

• automated test for everything visible from app side
• added a new button to in project test project (is 10s delay good?)
• manually tested on:
  • Nokia 7 Plus (10.0)
  • Asys ROG Phone (8.1)
  • Samsung Galaxy S7 (7.0)

Guidelines for testing:

• Android only
• should not depend neither on Unity nor Android version, but probably worth to do a simple check on lowest possible of both
• the in package test project should report received notification in it's console all the time, but not display notification in system status bar when ShowInForeground is false
• reschedule after reboot: all pieces tested automatically or manually, but the actual physical reboot with scheduled notification with or without this flag and result with app not launched, launched, but in foreground or with running in foreground needs to be checked
• you can manipulate what in package test project buttons do (or add new ones) in Resources folder; I think in general one button is enough looking forward; note, that if you create new buttons (Asset creation menu) yourself, I reported a bug to Editor that menu items don't correspond to actions (in my case the last menu item was for Android)

I see there's branch confilcts in: com.unity.mobile.notifications/Runtime/Android/Plugins/com/unity/androidnotifications/UnityNotificationManager.java

I've encountered an issue on OS: 5.0.1 device (Samsung Galaxy S4, ) and 5.0.2 ( HTC One M9+), where application crashes on launch

I do not have 5.1 device, therefore not sure if it's affected, but I think this should be addressed.
