* Merged commit includes the following changes:
311933687  by Sergio Guadarrama:

    Removes spurios use of tf.compat.v2, which results in spurious tf.compat.v1.compat.v2. Adds basic test to nasnet_utils.
    Replaces all remaining import tensorflow as tf with import tensorflow.compat.v1 as tf

--
311766063  by Sergio Guadarrama:

    Removes explicit tf.compat.v1 in all call sites (we already import tf.compat.v1, so this code was  doing tf.compat.v1.compat.v1). The existing code worked in latest version of tensorflow, 2.2, (and 1.15) but not in 1.14 or in 2.0.0a, this CL fixes it.

    Explicitly mark base models' state inputs as 'raw_inputs/init_lstm_h_1' and 'raw_inputs_init_lstm_h_2' when pre_bottleneck=True.

--
298380851  by skligys:

--
297662737  by Menglong Zhu:

    Explicitly replace "import tensorflow" with "tensorflow.compat.v1" for TF2.x migration

* Manually quantize selected inputs before summing them up.

* Fix messy variable paths in LSTD head.

With a VariableScope passed as parameter into tf.variable_scope(),
TF gets all confused and starts placing variables into scopes different
from operations (variable_scope != name_scope).  That leads to very messy
TF graphs.

* Add a second expected_loss_weights function using an alternative expectation calculation compared to previous. Integrate this op into ssd_meta_arch and losses builder. Affects files that use losses_builder.build to handle the returning of an additional element.
