Support timestamps as prefixes for traceback log lines.

Traceback lines in the log are now formatted to match other log
lines. So, instead of getting something like:

2012-03-26 14:53:26 ERROR nova.rpc.common [-] AMQP server on 10.55.58.1:5672 is unreachable: Socket closed. Trying again in 1 secon
ds.
(nova.rpc.common): TRACE: Traceback (most recent call last):
(nova.rpc.common): TRACE:   File "/usr/lib/python2.7/dist-packages/nova/rpc/impl_kombu.py", line 446, in reconnect
(nova.rpc.common): TRACE:     self._connect()
(nova.rpc.common): TRACE:   File "/usr/lib/python2.7/dist-packages/nova/rpc/impl_kombu.py", line 423, in _connect
(nova.rpc.common): TRACE:     self.connection.connect()

You would get something like:

2012-03-26 14:53:26 ERROR nova.rpc.common [-] AMQP server on 10.55.58.1:5672 is unreachable: Socket closed. Trying again in 1 secon
ds.
