Update unit test
Replace invalid warcfilename variable in playback
Stop using WarcRecord.REFERS_TO header and use payload_digest instead
Replace ``_split_timestamp`` with ``datetime.strptime`` in
``warcprox.dedup``.
Remove ``isinstance()`` and add optional ``record_url`` in the rest of
the dedup ``lookup`` methods.
Make `--cdxserver-dedup` option help more explanatory.
Add multiple ``CdxServerDedup`` unit tests to simulate found, not found and
invalid responses from the CDX server. Use a different file
``tests/test_dedup.py`` because we test the CdxServerDedup component
individually and it belongs to the ``warcprox.dedup`` package.
Add ``mock`` package to dev requirements.
Rework the warcprox.dedup.CdxServerDedup class to have better exception
handling.
Similarly with my previous commits, these methods do nothing.
I think that the reason they are here is because the author uses the
same style in other places in the code (e.g.
``warcprox.stats.StatsDb``). Similar methods exist there.
I'm trying to implement another DedupDb interface and I looked into the
use of each method. The ``close`` method of ``dedup.DedupDb`` and
``deup.RethinkDedupDb`` is empty.
It is also invoked from ``controller``.
Since it doesn't do anything and it won't in the foreseeable future,
let's remove it.
