The ApplyUpdates() method on the reputation.DB interface acts like the
similar Update() method, but can allow for applying the changes from
multiple audit events, instead of only one.
This will be necessary for the reputation write cache, which will batch
up changes to each node's reputation in order to flush them
periodically.

This has been a cause of some confusion, even though the fields are
labeled as being copies of config values.
Having them be under a field explicitly named "Config" makes this
clearer, plus, allows the values to be passed in simply as a copy
of the Config struct from the satellite, rather than copying the fields
individually (which can be error-prone, particularly as the AuditCount
field in UpdateRequest is apparently not the same thing as the
AuditCount field in reputation.Config).

We added nodes.disqualification_reason recently, but we didn't add a
corresponding column in the reputations table (despite having a
corresponding `disqualified` column there).
Without this change, the (very useful and informative) assignments to
updateFields.DisqualificationReason in reputations.go have no effect.

Set disqualification reason when reputations stats are updated on DB.Update.
Added tests for DisqualifyNode and for disqualification cases which happens during Update.

inconsistency
The original design had a flaw which can potentially cause discrepancy
for nodes reputation status between reputations table and nodes table.
In the event of a failure(network issue, db failure, satellite failure, etc.)
happens between update to reputations table and update to nodes table, data
can be out of sync.
This PR tries to fix above issue by passing through node's reputation from
the beginning of an audit/repair(this data is from nodes table) to the next
update in reputation service. If the updated reputation status from the service
is different from the existing node status, the service will try to update nodes
table. In the case of a failure, the service will be able to try update nodes
table again since it can see the discrepancy of the data. This will allow
both tables to be in-sync eventually.

package in audit
This PR implements reputation store and replace overlay in audit service
to use such store for storing node's audit stats.
In order to keep the changeset smaller, most of the changes in this PR is for copying audit logic in overlay to
reputation package. In a following PR, the duplicating code will be
removed from overlay.
