Delete android.net.PskKeyManager
android.net.PskKeyManager was @remove'd in Android O (API Level 26)
which means it may still be available on Android O platform, but is
not part of its public API. This commit deletes this class from
future platform versions.
The reasoning for the removal of this class is that:
1. it is incompatible with TLS 1.3, and
2. TLS-PSK cannot be exposed as a standalone primitive in a safe by
default way. There is no way for such primitive to ensure that
it is used with a shared secret which is not hard-coded into the
app or is otherwise publicly known.
Test: make
Test: Run a test app which uses PskKeyManager -- the app crashes
because the class is not found
