Corrects broken format strings in check_i18n.py

In tools/check_i18n.py, the error messages printed out
had format strings that included 5 interpolations, but only
four variables were supplied. This patch simply corrects that
mismatch by including the name of the predicate or checker
that failed.

Fix race in get_network(s) in OVS plugin

Load network bindings eagerly with networks.
Otherwise a different db query could try to fetch network bindings
for already deleted networks. The issue is reproducible with
concurrent tempest network API tests.

Rename nicira configuration elements to match new naming structure

- Every config item prefixed with nvp is prefixed with nsx
- deprecation qualifiers are added to preserve bw compatibility
- nicira/nvp.ini is renamed to vmware/nsx.ini
- symlink nicira/nvp.ini is created to point to vmware/nsx.ini
- UT added to verify that nvp.ini and old config items can still
  parsed correctly; bw-compat will be dropped in Juno
