Introducing Storage connector Interface (#12874)
In the current druid code base, we have the interface DataSegmentPusher which allows us to push segments to the appropriate deep storage without the extension being worried about the semantics of how to push too deep storage.

While working on #12262, whose some part of the code will go as an extension, I realized that we do not have an interface that allows us to do basic "write, get, delete, deleteAll" operations on the appropriate deep storage without let's say pulling the s3-storage-extension dependency in the custom extension.

Hence, the idea of StorageConnector was born where the storage connector sits inside the druid core so all extensions have access to it.

Each deep storage implementation, for eg s3, GCS, will implement this interface.
Now with some Jackson magic, we bind the implementation of the correct deep storage implementation on runtime using a type variable.

Able to filter Cloud objects with glob notation. (#12659)
In a heterogeneous environment, sometimes you don't have control over the input folder. Upstream can put any folder they want. In this situation the S3InputSource.java is unusable.

Most people like me solved it by using Airflow to fetch the full list of parquet files and pass it over to Druid. But doing this explodes the JSON spec. We had a situation where 1 of the JSON spec is 16MB and that's simply too much for Overlord.

This patch allows users to pass {"filter": "*.parquet"} and let Druid performs the filtering of the input files.

I am using the glob notation to be consistent with the LocalFirehose syntax.

Always reopen stream in FileUtils.copyLarge, RetryingInputStream. (#12307)
* Always reopen stream in FileUtils.copyLarge, RetryingInputStream.

When an InputStream throws an exception from one of its read methods,
we should assume it's bad and reopen it.

The main changes here are:

- In FileUtils.copyLarge, replace InputStream with InputStreamSupplier.
- In RetryingInputStream, collapse retryCondition and resetCondition
  into a single condition. Also, make it required, since every usage
  is passing in a specific condition anyway.

* Test fixes.

* Fix read impl.

update jackson dependencies to use bom (#11353)
Switching to the bom dependency declaration simplifies managing jackson
dependencies. It also removes the need to override individual library
versions for CVE fixes, since the bom takes care of that internally.

This change aligns our jackson dependency versions on 2.10.5(.x):
- updates jackson libraries from 2.10.2 to 2.10.5
- jackson-databind remains at 2.10.5.1 as defined in the bom

DruidInputSource: Fix issues in column projection, timestamp handling. (#10267)
* DruidInputSource: Fix issues in column projection, timestamp handling.

DruidInputSource, DruidSegmentReader changes:

1) Remove "dimensions" and "metrics". They are not necessary, because we
   can compute which columns we need to read based on what is going to
   be used by the timestamp, transform, dimensions, and metrics.
2) Start using ColumnsFilter (see below) to decide which columns we need
   to read.
3) Actually respect the "timestampSpec". Previously, it was ignored, and
   the timestamp of the returned InputRows was set to the `__time` column
   of the input datasource.

(1) and (2) together fix a bug in which the DruidInputSource would not
properly read columns that are used as inputs to a transformSpec.

(3) fixes a bug where the timestampSpec would be ignored if you attempted
to set the column to something other than `__time`.

(1) and (3) are breaking changes.

Web console changes:

1) Remove "Dimensions" and "Metrics" from the Druid input source.
2) Set timestampSpec to `{"column": "__time", "format": "millis"}` for
   compatibility with the new behavior.

Other changes:

1) Add ColumnsFilter, a new class that allows input readers to determine
   which columns they need to read. Currently, it's only used by the
   DruidInputSource, but it could be used by other columnar input sources
   in the future.
2) Add a ColumnsFilter to InputRowSchema.
3) Remove the metric names from InputRowSchema (they were unused).
4) Add InputRowSchemas.fromDataSchema method that computes the proper
   ColumnsFilter for given timestamp, dimensions, transform, and metrics.
5) Add "getRequiredColumns" method to TransformSpec to support the above.

* Various fixups.

Allow Cloud Deep Storage configs without segment bucket or path specified (#9588)
* Allow Cloud SegmentKillers to be instantiated without segment bucket or path

This change fixes a bug that was introduced that causes ingestion
to fail if data is ingested from one of the supported cloud storages
(Azure, Google, S3), and the user is using another type of storage
for deep storage. In this case the all segment killer implementations
are instantiated. A change recently made forced a dependency between
the supported cloud storage type SegmentKiller classes and the
deep storage configuration for that storage type being set, which
forced the deep storage bucket and prefix to be non-null. This caused
a NullPointerException to be thrown when instantiating the
SegmentKiller classes during ingestion.

To fix this issue, the respective deep storage segment configs for the
cloud storage types supported in druid are now allowed to have nullable
bucket and prefix configurations

S3: Improvements to prefix listing (including fix for an infinite loop) (#9098)
* S3: Improvements to prefix listing (including fix for an infinite loop)

1) Fixes #9097, an infinite loop that occurs when more than one batch
   of objects is retrieved during a prefix listing.

2) Removes the Access Denied fallback code added in #4444. I don't think
   the behavior is reasonable: its purpose is to fall back from a prefix
   listing to a single-object access, but it's only activated when the
   end user supplied a prefix, so it would be better to simply fail, so
   the end user knows that their request for a prefix-based load is not
   going to work. Presumably the end user can switch from supplying
   'prefixes' to supplying 'uris' if desired.

3) Filters out directory placeholders when walking prefixes.
