By accident query to get latest table stats was ordered by 'row_count'
column instead 'create'. We need latest stats so we need ordering by
creation time.

We want to eliminate usages of LoopSegmentEntry.Pieces, because it is
costing a lot of cpu time to look up node IDs with every piece of every
segment we read.
In this change, we are eliminating use of LoopSegmentEntry.Pieces in the
node tally observer (both the ranged loop and segments loop variants).
It is not necessary to have a fully resolved nodeID until it is time to
store totals in the database. We can use NodeAliases as the map key
instead, and resolve NodeIDs just before storing totals.

Currently, to get number of entries in segments table we are doing
heavy SELECT count(*) operation. For biggest satellite it's taking
25min now. We are using this method to get stat before and after
segments loop so it adds almost 1h to overall loop time.
With current version of crdb we are using this additional code won't be
used because global configuration for stats refresh rate is inaccurate
for such large table like `segments`. Soon we should be able to upgrade
crdb and be able to adjust refresh rate per table and configure it to
satisfy defined threshold.

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 is first attempt to use AliasPieces inastead Pieces with
segments/range loop. So far we were always using Pieces
which are always converted from AliasPieces for easy use.
Side effect is that using NodeID with loop observers is heavy
e.g. we are using maps which behaves slower with NodeIDs.
We are starting with audit observer because it's easy to change
it as in feact it doesn't need access to real NodeID at all. We just
need to reference node in some way and this way is NodeAlias.

We have an issue where object can appear in two different listing pages.
It's because protobuf listing cursor doesn't have version included and
now we can have internally versions higher than 1. On satellite side
version 1 was always used as a default cursor version.
As a workaround for existing implementation of libuplink library we will
use always maximum version for listing cursor on satellite side.
Fixing protobuf and libuplink implementation will happen later.

This is automated test around metabase tests. It's detecting queries

Small cleanups of the observer stats init code:
1. Use sync.Once for race free addition to the monitoring chain
(purely defensive)
2. Set the observer durations before adding to the monitoring chain on
first use.
3. observerDurations slice does not need to be initialized to non-nil

When an observer errors we still want to finish the other observers.
This changes store the error and continues the loop, skipping
the observer which errored out and setting the duration metric to -1.
When the error occurs in the process stage, it does continue the other
ranges of the same observer. It removes the observer entirely after the process
stage. To improve this would make it more complex due to race
conditions.

Before we introduced objects versions internally move operation was
always failing when under target location object exists. But then we
had only single version 1 all the time. With versions different than 1
we need to check all existing objects under target location.
To be backward compatible with our API new logic looks like this:
* if there is no object under target location use source object version
as target version
* if there are only pending objects find first free (highest) version
which could be used to move object there
* if there is committed object under target location reject move
operation

Some observers assume that they will observe all the segments for a
given stream, and that they will observe those segments in a sequential
stream over one or more iterations.
This change updates the range provider from rangedlooptest to provide
these guarantees.
The change also removes the Mock suffix from the provider/splitter types
since the package name (rangedlooptest) implies that the type is a test
double.

We have a bug in our behavior while doing API pods deployment. At this
time its possible to have pods with multiple versions flag set true only
partially for some of pods. Because of that it's possible to start new
object without removing existing/older version on BeginObject
(new behavior) and also don't remove that existing/older object on
CommitObject. That can cause to have two committed objects with
different versions and that's a state we want to avoid.
To fix it we are removing multiple versions flag from CommitObject to
always try delete existing objects. This way even if we don't remove
existing object on BeginObject it will be always removed while
committing.
