Adding Custom-Time to Firebase Storage

[nathanfallet]

What feature would you like to see?

As reported and implemented in the firebase-ios-sdk in firebase/firebase-ios-sdk#9576, the Custom-Time property is missing in Firebase Storage Metadatas. The idea is to implement it as well in firebase-android-sdk.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @nathanfallet, thanks for filing the request. Our engineers will take a look at this when they have the time.

Please note that the backend is not fully supporting the feature (as we noticed by implementing it in the iOS SDK), so it will need backend changes.

Well noted!
