LiveQuery support for the Parse Config

New Feature / Enhancement Checklist

Current Limitation

Currently there's no way to listen for a changes on Parse Config.

Feature / Enhancement Description

If LiveQuery can start support Parse Config this will be awesome as it can listen for changes on the configuration and apply them runtime. Firebase Remote Config for example uses pulling, where the LiveQuery can make it even better.

Firebase pulling:

val remoteConfig = Firebase.remoteConfig
val configSettings = remoteConfigSettings {
    minimumFetchIntervalInSeconds = 3600
}
remoteConfig.setConfigSettingsAsync(configSettings)

Example Use Case

Feature flags is a good candidate for example use case. Developers can store feature flags data in Parse Config and the apps can
listen for changes using the LiveQuery and trigger features server side.

Alternatives / Workarounds

1. Custom implementation using pulling and using platform specific SDKs Parse Config APIs.
2. Creating custom Parse class handling the remote configuration or feature flags (this invalidated the Parse Config feature) and use the LiveQuery with it.

Start by examining the existing Parse Config and LiveQuery behavior described in the issue. No files, tests, or implementation entry points are named, so first identify where each feature is handled and how changes are propagated. Done should provide a defined way for clients to receive Parse Config changes at runtime.
