Avatar Etags

[tobiasKaminsky]

Resolves #1566

This caches the etag of an avatar and sends the etag to server and gets

• a new avatar if etag changed -> use new one
• a 304 response, meaning nothing changed -> show old avatar

Edit: not query the server too often we could also implement a 15min timeout, or whatever time.

Once nextcloud/server#6876 is merged the problem should be solved as we then always have a bitmap.

nextcloud/server#6876 is merged :)

[tobiasKaminsky]

nextcloud/server#6876 is independent from this PR as it is NC13 only.
Once NC13 is our oldest supported release we can remove

android/src/main/java/com/owncloud/android/ui/TextDrawable.java

Line 97 in c7ee4f1

public static TextDrawable createAvatar(String accountName, float radiusInDp) throws

Annotated via custom annotation. The idea is that we can use this for tracking code parts which we can later remove. In this case, if min supported version is 13, we can safely delete this code.
