While the index shouldn't be necessary as long as our implementation is
correct, it still provides some additional checks for mistakes in the
implementation.

By using a separate function for deleting the latest object and
fetching the latest version we can simplify some of the code.
However, there can be more performant approaches, such as using
ON CONFLICT for updating the existing object or using select and delete
in the same query in databases that support it.

There are several different object types in a versioned table,
which will determine the exact behaviour.
The object type states are:
* Pending - the object is yet to be committed and is being uploaded.
* Committed - the object has been finished and can be read.
* DeleteMarker - indicates that the object should be treated as not
present when is at the top of the version stack.
There are also versioning states:
* Unversioned - only one unversioned object is allowed per object key.
* Versioned - multiple objects with the same key are allowed.

I believe that this change in semantics won't break anything, because
ListVerifySegments is only used by cmd/tools/segment-verify (which only
needs to operate on non-expired segments) and various tests, none of
which expect ListVerifySegments to include expired segments.

With the upcoming versioning changes `BeginObjectExactVersion` makes
only sense for testing. Currently this does not rename the options
struct or move it into `metabasetest`, because it would create a
significant amount of merge/rebase noise.

When we do `satellite run api --placement '...'`, the placement rules are not parsed well.
The problem is based on `viper.AllSettings()`, and the main logic is sg. like this (from a new unit test):
```
r := ConfigurablePlacementRule{}
err := r.Set(p)
require.NoError(t, err)
serialized := r.String()
r2 := ConfigurablePlacementRule{}
err = r2.Set(serialized)
require.NoError(t, err)
require.Equal(t, p, r2.String())
```
All settings evaluates the placement rules in `ConfigurablePlacementRules` and stores the string representation.
The problem is that we don't have proper `String()` implementation (it prints out the structs instead of the original definition.
There are two main solutions for this problem:
1. We can fix the `String()`. When we parse a placement rule, the `String()` method should print out the original definition
2. We can switch to use pure string as configuration parameter, and parse the rules only when required.
I feel that 1 is error prone, we can do it (and in this patch I added a lot of `String()` implementations, but it's hard to be sure that our `String()` logic is inline with the parsing logic.
Therefore I decided to make the configuration value of the placements a string (or a wrapper around string).
That's the main reason why this patch seems to be big, as I updated all the usages.
But the main part is in beginning of the `placement.go` (configuration parsing is not a pflag.Value implementation any more, but a separated step).
And `filter.go`, (a few more String implementation for filters.

Currently it wasn't quite clear what was a stub version and an actual
version. Use a PendingVersion constant to make this distinction clear.
Also use PendingVersion = NextVersion = 0, that way it's clearer that
the version hasn't been yet determined. DefaultVersion = 1 might imply
that the object will get that version once commited, however that will
entirely depend on whether use-pending-objects is used or versioning is
enabled or not.

While adding support for pending_objects table one case was missed.
When we are uploading object to location where old objects exists
we are not removing old object segments at all. Old object is
overwritten with new object metadata but segments remains without
corresponding object. This fix removes all existing committed objects
(with it's segments) before committing new object.

Implementation and tests are mostly copy of code for

Method will be used to support new table in

placement.AllowedCountry is the old way to specify placement, with the new approach we can use a more generic (dynamic method), which can check full node information instead of just the country code.
The 90% of this patch is just search and replace:
* we need to use NodeFilters instead of placement.AllowedCountry
* which means, we need an initialized PlacementRules available everywhere
* which means we need to configure the placement rules
The remaining 10% is the placement.go, where we introduced a new type of configuration (lightweight expression language) to define any kind of placement without code change.

..instead of using segment_copies and ancestor_stream_id, etc.
This bypasses reference counting entirely, depending on our mark+sweep+
bloomfilter garbage collection strategy to get rid of pieces once they
are no longer part of a segment.
This is only safe to do after we have stopped passing delete requests on
to storage nodes.

Currently we are using Reliable to get missing pieces for repair
checker. The issue is that now checker is looking at more things than
just missing pieces (clumped/off, placement pieces) and using only node
ID is not enough. We have issue where we are skipping offline nodes from
clumped and off placement pieces check.
Reliable was refactored to get data (e.g. country, lastNet) about all
reliable nodes. List is split into online and offline. This data will be
cached for quick use by repair checker. It will be also possible to
check nodes metadata like country code or lastNet.
We are also slowly moving `RepairExcludedCountryCodes` config from
overlay to repair which makes more sens for it.
