Deprecate old models

Update to tf 1.14 syntax, fix bug #7125 (needed additional expand for conv2d).  Suppress compat warnings by moving to compat.v1 versions of some functions.  Note that this code is not 2.0 compatible yet - that will be a future push. (#7177)

Make the progress printed from the adversarial crypto example
print columns in a consistently-formatted way.

* eve_optimizer --> ac.eve_optimizer
* reset_eve_vars --> ac.reset_eve_vars
* eve_optimizer --> ac.eve_optimizer

According to the code below:
```python
if key is not None:
      combined_message = tf.concat(axis=1, values=[message, key])
else:
      combined_message = message
```python
If the key=None, combined_message is just message, not the key.
