* satellite/satellitedb: Alter nodes disqualification column
Change the type of the 'disqualification' column of the nodes table from
boolean to timestamp.
* overlay/cache: Change Disqualified field type
Change the Disqualified field type the NodeDossier struct type from bool
to time.Time to match with the disqualified type used by the DB layer.
* satellite/satellitedb: Update queries uses disqualified
Update the queries which uses the disqualified column due to the column
type has been changed from boolean to nullable timestamp.
* docs/design: Update disqualification due impl changes
Update the disqualification design document to contain the architectural
change required to be able to restore unfair disqualified nodes in case
of an unexpected cause (bug, mistake, hard network disconnection, etc.).
* reputation: Add configuration parameters
Add the configuration parameters which will be used by the algorithm
which will calculate the storage node reputation.
Because the reputation calculation is based on audit and uptime check
results some configuration parameters are in pkg/audit, others in
pkg/discovery and other in the satellite which will combine the both
reputation results to obtain the storage node reputation for repair and
uplink.
* satellite-config: Refresh lock file with new params
Refresh the Satellite configuration yaml lock file with the new
parameters added in this branch.
* set up voucher service skeleton, basic test
* add VetNode db method
* basic test for VetNode
* encode and sign voucher functions
* fill out and sign vouchers
* test pass/fail voucher request
* match EncodeVoucher to other Encode functions
* add last_ip field to dbx model node, generate dbx
* add last_ip to node proto, generate pb
* migrate
* resolve address in transport.DialNode, update lastIp in cache.UpdateAddress
* use net.SplitHostPort to isolate host address from port
* define DistinctIPs flag

* if distinctIPs flag == true, query for nodes with distinct IPs
* some basic tests
* change last_ip to field 14 in proto
* remove comments
* check err
* change distinctIPs to distinctIP
* exclude IPs from newNodes in query for reputable nodes
* add index on last_ip
* only add to excludedIPs if flag is true
* test half new nodes returns distinct IPs
* fix alignment
* add test
* rework ip filter query, add retry logic, add switch for database driver
* add retry to SelectNewNodes
* change discovery intervals so IPs don't get overwritten
* remove TestGetIP
* edit updating node stats in test
* split exclude into nodeIDs and IPs
* separate non-distinct IP query into other function
* trigger checks
* remove else block
