The new version of this crate properly sets a lease duration such that the locks
can actually expire

# Description

Introduce a `LogStore` abstraction to channel all log store reads and
writes through a single place. This is supposed to allow implementations
with more sophisticated locking mechanisms that do not rely on atomic
rename semantics for the underlying object store.

This does not change any functionality - it reorganizes read operations
and commits on the delta commit log to be funneled through the
respective methods of `LogStore`.

## Rationale

The goal is to align the implementation of multi-cluster writes for
Delta Lake on S3 with the one provided by the original `delta` library,
enabling multi-cluster writes with some writers using Spark / Delta
library and other writers using `delta-rs` For an overview of how it's
done in delta, please see:
1. Delta [blog
post](https://delta.io/blog/2022-05-18-multi-cluster-writes-to-delta-lake-storage-in-s3/)
(high-level concept)
2. Associated Databricks [design
doc](https://docs.google.com/document/d/1Gs4ZsTH19lMxth4BSdwlWjUNR-XhKHicDvBjd2RqNd8/edit#heading=h.mjjuxw9mcz9h)
(detailed read)
3.
[S3DynamoDbLogStore.java](https://github.com/delta-io/delta/blob/master/storage-s3-dynamodb/src/main/java/io/delta/storage/S3DynamoDBLogStore.java)(content
warning: Java code behind this link)

This approach requires readers of a delta table to "recover" unfinished
commits from writers - as a result, reading and writing is combined in a
single interface, which in this PR is modeled after
[LogStore.java](https://github.com/delta-io/delta/blob/master/storage/src/main/java/io/delta/storage/LogStore.java).
Currently in `delta-rs`, read path for commits is implemented directly
in `DeltaTable`, and there's no mechanism to implement storage-specific
behavior like interacting with DynamoDb.

# Description
I have made a bunch of improvements to fix the overall structure due to
example sections not being consistent. I've also enabled some extra
features. Fixed also the issue of some classes/functions not being shown
properly.

This is a continuation of the discussion in the

the library crate in favor of returning an error so lib users could
handle it in a way they see it Test changes accordingly
