Code Issues Proposed changes

Sync with oslo-incubator 

Remove obsoleted modules from tree.
Sync with oslo-incubator at commit
838a2a31fe009feb2501716d6656eeea426ea357.

The updated lockfile module needs setting of the lock_path option,
ensure that it is set in the testsuite.

In some cases the exception context can be cleared, resulting in None
being attempted to be re-raised after an exception handler is run. This
can happen when eventlet switches greenthreads or when running an
exception handler, code raises and catches an exception. In both
cases the exception context will be cleared.
To work around this, we save the exception state, run handler code, and
then re-raise the original exception. If another exception occurs, the
saved exception is logged and the new exception is re-raised.
In some cases the caller may not want to re-raise the exception, and
for those circumstances this context provides a reraise flag that
can be used to suppress the exception. For example::
except Exception:
with save_and_reraise_exception() as ctxt:
decide_if_need_reraise()
if not should_be_reraised:
ctxt.reraise = False
If another exception occurs and reraise flag is False,
the saved exception will not be logged.
If the caller wants to raise new exception during exception handling
he/she sets reraise to False initially with an ability to set it back to
True if needed::

JSON related utilities.
This module provides a few things:
1) A handy function for getting an object down to something that can be
JSON serialized. See to_primitive().
2) Wrappers around loads() and dumps(). The dumps() wrapper will
automatically use to_primitive() for you if needed.
3) This sets up anyjson to use the loads() and dumps() wrappers if anyjson
is available.
