This file was written on the assumption that bindService was
synchronous, which it isn't. This change adds a CountDownLatch to force
the class to wait for the binding to finish.
Bug: 190222116
Test: atest RemoteProvisionerUnitTests
Change-Id: I917a61da612f21f9a0f783bea5d24270d4e1db42
This change adds an AIDL interface which the RemoteProvisioner app
implements that allows the keystore SPI to inform the app when an
attestation key may have been used, and when the underlying attestation
key pool is totally empty. The former is a non-blocking call, and the
latter blocks until completion.
Since the latter involves network, there are timeouts involved on the
app side to ensure that the blocking call doesn't hang indefinitely if
there's no network.
