Support for hadoop 3 via maven profiles (#11794)
Add support for hadoop 3 profiles . Most of the details are captured in #11791 .
We use a combination of maven profiles and resource filtering to achieve this. Hadoop2 is supported by default and a new maven profile with the name hadoop3 is created. This will allow the user to choose the profile which is best suited for the use case.

Add druid.sql.approxCountDistinct.function property. (#11181)
* Add druid.sql.approxCountDistinct.function property.

The new property allows admins to configure the implementation for
APPROX_COUNT_DISTINCT and COUNT(DISTINCT expr) in approximate mode.

The motivation for adding this setting is to enable site admins to
switch the default HLL implementation to DataSketches.

For example, an admin can set:

  druid.sql.approxCountDistinct.function = APPROX_COUNT_DISTINCT_DS_HLL

Kafka Input Format for headers, key and payload parsing (#11630)
### Description

Today we ingest a number of high cardinality metrics into Druid across dimensions. These metrics are rolled up on a per minute basis, and are very useful when looking at metrics on a partition or client basis. Events is another class of data that provides useful information about a particular incident/scenario inside a Kafka cluster. Events themselves are carried inside kafka payload, but nonetheless there are some very useful metadata that is carried in kafka headers that can serve as useful dimension for aggregation and in turn bringing better insights.

PR(https://github.com/apache/druid/pull/10730) introduced support of Kafka headers in InputFormats.

We still need an input format to parse out the headers and translate those into relevant columns in Druid. Until that’s implemented, none of the information available in the Kafka message headers would be exposed. So first there is a need to write an input format that can parse headers in any given format(provided we support the format) like we parse payloads today. Apart from headers there is also some useful information present in the key portion of the kafka record. We also need a way to expose the data present in the key as druid columns. We need a generic way to express at configuration time what attributes from headers, key and payload need to be ingested into druid. We need to keep the design generic enough so that users can specify different parsers for headers, key and payload.

This PR is designed to solve the above by providing wrapper around any existing input formats and merging the data into a single unified Druid row.

Lets look at a sample input format from the above discussion

"inputFormat":
{
    "type": "kafka",     // New input format type
    "headerLabelPrefix": "kafka.header.",   // Label prefix for header columns, this will avoid collusions while merging columns
    "recordTimestampLabelPrefix": "kafka.",  // Kafka record's timestamp is made available in case payload does not carry timestamp
    "headerFormat":  // Header parser specifying that values are of type string
    {
        "type": "string"
    },
    "valueFormat": // Value parser from json parsing
    {
        "type": "json",
        "flattenSpec": {
          "useFieldDiscovery": true,
          "fields": [...]
        }
    },
    "keyFormat":  // Key parser also from json parsing
    {
        "type": "json"
    }
}

Since we have independent sections for header, key and payload, it will enable parsing each section with its own parser, eg., headers coming in as string and payload as json. 

KafkaInputFormat will be the uber class extending inputFormat interface and will be responsible for creating individual parsers for header, key and payload, blend the data resolving conflicts in columns and generating a single unified InputRow for Druid ingestion. 

"headerFormat" will allow users to plug parser type for the header values and will add default header prefix as "kafka.header."(can be overridden) for attributes to avoid collision while merging attributes with payload.

Kafka payload parser will be responsible for parsing the Value portion of the Kafka record. This is where most of the data will come from and we should be able to plugin existing parser. One thing to note here is that if batching is performed, then the code is augmenting header and key values to every record in the batch.

Kafka key parser will handle parsing Key portion of the Kafka record and will ingest the Key with dimension name as "kafka.key".

## KafkaInputFormat Class: 
This is the class that orchestrates sending the consumerRecord to each parser, retrieve rows, merge the columns into one final row for Druid consumption. KafkaInputformat should make sure to release the resources that gets allocated as a part of reader in CloseableIterator<InputRow> during normal and exception cases.

During conflicts in dimension/metrics names, the code will prefer dimension names from payload and ignore the dimension either from headers/key. This is done so that existing input formats can be easily migrated to this new format without worrying about losing information.

remove ZooKeeper 3.4 support + pass tests with Java 15 (#11073)
With this change, Druid will only support ZooKeeper 3.5.x and later.

In order to support Java 15 we need to switch to ZK 3.5.x client libraries and drop support for ZK 3.4.x
(see #10780 for the detailed reasons) 

* remove ZooKeeper 3.4.x compatibility
* exclude additional ZK 3.5.x netty dependencies to ensure we use our version
* keep ZooKeeper version used for integration tests in sync with client library version
* remove the need to specify ZK version at runtime for docker
* add support to run integration tests with JDK 15
* build and run unit tests with Java 15 in travis

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.
