Adding unit test to ShadowBluetoothGatt

[Kevin Lockwood]

There is a missing API call in ShadowBluetoothGatt I would like to add, as its needed for a full API state machine test.  BluetoothGatt#setPreferredPhy.  I have a tentative CL I would like to push in g3 on Critique.  Who would be best to assign as reviewers?

There are two other new APIs in BluetoothGatt/BluetoothGattCallback that I would eventually like to add as well to keep this Shadow up to date with current available APIs.

Thanks,

KL

Perhaps bad nomenclature.  I mean add new API to ShadowBluetoothGatt (setPreferredPhy),  for production code unit testing.
