This code is essentially replacement for eestream.CalcPieceSize. To call
eestream.CalcPieceSize we need eestream.RedundancyStrategy which is not
trivial to get as it requires infectious.FEC. For example infectious.FEC
creation is visible on GE loop observer CPU profile because we were
doing this for each segment in DB.
New method was added to storj.Redundancy and here we are just wiring it
with metabase Segment.

This commit pulls the big switch! We have been setting up piecewise
reverifications (the workers for which can be scaled independently of
the core) for several commits now, and this commit actually begins
making use of them.
The core of this commit is fairly small, but it requires changing the
semantics in all the tests that relate to reverifications, so it ends up
being a large change. The changes to the tests are mostly mechanical and
repetitive, though, so reviewers needn't worry much.

First, adding a logger argument allows the caller to have a logger
already set up with whatever extra fields they want here.
Secondly, we need to return the Outcome instead of a simple boolean so
that it can be passed on to the Reporter later (need to make the right
decision on increasing reputation vs decreasing it).
Thirdly, we collect the cached reputation information from the overlay
when creating the Orders, and return it from ReverifyPiece. This will
allow the Reporter to determine what reputation-status fields need to be
updated, similarly to how we include a map of ReputationStatus objects
in an audit.Report.

Adding a new worker comparable to Verifier, called Reverifier; as the
name suggests, it will be used for reverifications, whereas Verifier
will be used for verifications.
This allows distinct logging from the two classes, plus we can add some
configuration that is specific to the Reverifier.
There is a slight modification to GetNextJob that goes along with this.
This should have no impact on operational concerns.

GetByNodeID will allow querying the reverification queue to see if there
are any pending jobs for a given node ID. And thus, to see if that node
ID should be contained or not.
Some parameters on the other methods of the ReverifyQueue interface have
been changed to accept pointers; this was done ahead of the rest of the
changes for the reverification queue to better match the signatures of
the methods that these will replace once ReverifyQueue is actually being
used (meaning fewer changes to tests).

ReverifyPiece() is not currently hooked up to anything, but is planned
to take the place of audit.(*Verifier).Reverify().
ReverifyPiece() works by downloading one piece in its entirety, rather
than pulling an entire stripe across many nodes.

This table will be used as a queue for pieces that need to be reverified
(a regular audit timed out on the owning node, so now that node is
contained and we need to validate the piece before un-containing it).
