Robert Kukura 922dae45d0 Add unit tests for ML2 DVR port binding and fix PortContext inconsistencies
Extends the existing ML2 port binding unit tests to cover the
distributed port bindings used for DVR. Within the test mechanism
driver, bindings are tracked per-host, and additional assertions are
added.

Fixes issues with PortContext attributes that were exposed by these
new tests. Adds new vif_type, original_vif_type, vif_details, and
original_vif_details PortContext attributes, similar to the exising
host, original_host, status, and original_status attributes, to
reflect host-specific details of distributed (or normal) port
bindings. Also fixes original_host and original_status to return None
when in the context of an operation other than an update, and fixes
original_host to reflect the specific host being bound for a
distributed port.
