Port rescue API to v3 Part 1

This changeset only copies the v2 files (implementation and test)
into the appropriate v3 directories unchanged. The copy as-is
will not be loaded by either the v2 or v3 extension loaders. The
second changeset will then make the changes required for it to
work as a v3 extension.

This is being tried in order to make reviewing of extension
porting easier as gerrit will display only what is actually
changed for v3 rather than entirely new files

Partially implements blueprint nova-v3-api

refactor security group api not to raise http exceptions

The SecurityGroupAPI had been raising http exceptions,
resulting in a difference in behavior depending on the
driver being used: nova or quantum. The nova driver
re-raises nova exceptions by default, while the quantum
driver was raising the built-in http exceptions. Since
servers.py handles nova exceptions, in some cases the
quantum driver's http exceptions weren't being handled
and resulted in a different http return code to the
user.

Both SecurityGroupAPI classes inherit from
NativeSecurityGroupExceptions and call its static
methods to raise exceptions.

This change refactors SecurityGroupAPI to raise nova
exceptions by modifying NativeSecurityGroupExceptions.
The nova exceptions are then translated to http
exceptions in the security group wsgi extension.

Fixes bug 1183347
