Filter http requests by http method (#10085)
* Filter http requests by http method

Add a config that allows a user which http methods to allow against their
Druid server.

Druid will only accept http requests with the method: GET, PUT, POST, DELETE
and OPTIONS.
If a Druid admin wants to allow other methods, they can do so by using the
ServerConfig#allowedHttpMethods config.

If a Druid user would like to disallow OPTIONS, this can be done by changing
the AuthConfig#allowUnauthenticatedHttpOptions config

* Exclude OPTIONS from always supported HTTP methods

Add HEAD as an allowed method for web console e2e tests

* fix docs

* fix security IT

* Actually fix the web console e2e tests

* Ignore icode coverage for nitialization classes

* code review

Refresh query docs. (#9704)
* Refresh query docs.

Larger changes:

- New doc: querying/datasource.md describes the various kinds of
datasources you can use, and has examples for both SQL and native.
- New doc: querying/query-execution.md describes how native queries
are executed at a high level. It doesn't go into the details of specific
query engines or how queries run at a per-segment level. But I think it
would be good to add or link that content here in the future.
- Refreshed doc: querying/sql.md updated to refer to joins, reformatted
a bit, added a new "Query translation" section that explains how
queries are translated from SQL to native, and removed configuration
details (moved to configuration/index.md).
- Refreshed doc: querying/joins.md updated to refer to join datasources.

Smaller changes:

- Add helpful banners to the top of query documentation pages telling
people whether a given page describes SQL, native, or both.
- Add SQL metrics to operations/metrics.md.
- Add some color and cross-links in various places.
- Add native query component docs to the sidebar, and renamed them so
they look nicer.
- Remove Select query from the sidebar.
- Fix Broker SQL configs in configuration/index.md. Remove them from
querying/sql.md.
- Combined querying/searchquery.md and querying/searchqueryspec.md.

* Updates.

* Fix numbering.

* Fix glitches.

* Add new words to spellcheck file.

* Assorted changes.

* Further adjustments.

* Add missing punctuation.

SQL support for joins on subqueries. (#9545)
* SQL support for joins on subqueries.

Changes to SQL module:

- DruidJoinRule: Allow joins on subqueries (left/right are no longer
  required to be scans or mappings).
- DruidJoinRel: Add cost estimation code for joins on subqueries.
- DruidSemiJoinRule, DruidSemiJoinRel: Removed, since DruidJoinRule can
  handle this case now.
- DruidRel: Remove Nullable annotation from toDruidQuery, because
  it is no longer needed (it was used by DruidSemiJoinRel).
- Update Rules constants to reflect new rules available in our current
  version of Calcite. Some of these are useful for optimizing joins on
  subqueries.
- Rework cost estimation to be in terms of cost per row, and place all
  relevant constants in CostEstimates.

Other changes:

- RowBasedColumnSelectorFactory: Don't set hasMultipleValues. The lack
  of isComplete is enough to let callers know that columns might have
  multiple values, and explicitly setting it to true causes
  ExpressionSelectors to think it definitely has multiple values, and
  treat the inputs as arrays. This behavior interfered with some of the
  new tests that involved queries on lookups.
- QueryContexts: Add maxSubqueryRows parameter, and use it in druid-sql
  tests.

* Fixes for tests.

Chi Cao Minh 14a8613d69 Exit JVM on curator unhandled errors (#8458)
* Exit JVM on curator unhandled errors

If an unhandled error occurs when curator is talking to ZooKeeper, exit
the JVM in addition to stopping the lifecycle to prevent the process
from being left in a zombie state. With this change,
BoundedExponentialBackoffRetryWithQuit is no longer needed as when
curator exceeds the configured retries, it triggers its unhandled error
listeners. A new "connectionTimeoutMs" CuratorConfig setting is added
mostly to facilitate testing curator unhandled errors, but it may be
useful for users as well.
