* Two fixes related to encoding of % symbols.
1) TaskResourceFilter: Don't double-decode task ids. request.getPathSegments()
returns already-decoded strings. Applying StringUtils.urlDecode on
top of that causes erroneous behavior with '%' characters.
2) Update various ThreadFactoryBuilder name formats to escape '%'
characters. This fixes situations where substrings starting with '%'
are erroneously treated as format specifiers.
ITs are updated to include a '%' in extra.datasource.name.suffix.
* Avoid String.replace.

* Fix handling of 'join' on top of 'union' datasources.
The problem is that unions are typically rewritten into a series of
individual queries on the underlying tables, but this isn't done when
the union is wrapped in a join.
The main changes are in UnionQueryRunner:
1) Replace an instanceof UnionQueryRunner check with DataSourceAnalysis.
2) Replace a "query.withDataSource" call with a new function, "Queries.withBaseDataSource".
Together, these enable UnionQueryRunner to "see through" a join.

* Join filter pre-analysis simplifications and sanity checks.
- At pre-analysis time, only compute pre-analysis for the innermost
root query, since this is the one that will run on the join that involves
the base datasource. Previously, pre-analyses were computed for multiple
levels of the query, some of which were unnecessary.
- Remove JoinFilterPreAnalysisGroup and join query level gathering code,
since they existed to support precomputation of multiple pre-analyses.
- Embed JoinFilterPreAnalysisKey into JoinFilterPreAnalysis and use it to
sanity check at processing time that the correct pre-analysis was done.
Tangentially related changes:
- Remove prioritizeAndLaneQuery functionality from LocalQuerySegmentWalker.
The computed priority and lanes were not being used.
- Add "getBaseQuery" method to DataSourceAnalysis to support identification
of the proper subquery for filter pre-analysis.
* Fix compilation errors.
* Adjust tests.
* Make brokers backwards compatible
In 0.19, Brokers gained the ability to serve segments. To support this change,
a `BROKER` ServerType was added to `druid.server.coordination`.
Druid nodes prior to this change do not know of this new server type and so
they would fail to deserialize this node's announcement.
This change makes it so that the broker only announces itself if the segment
cache is configured on the broker. It is expected that a Druid admin will only
configure the segment cache on the broker once the cluster has been upgraded
to a version that supports a broker using the segment cache.

* code review
* 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

This change removes ListenableFutures.transformAsync in favor of the
existing Guava Futures.transform implementation. Our own implementation
had a bug which did not fail the future if the applied function threw an
exception, resulting in the future never completing.
An attempt was made to fix this bug, however when running againts Guava's own
tests, our version failed another half dozen tests, so it was decided to not
continue down that path and scrap our own implementation.
Explanation for how was this bug manifested itself:
An exception thrown in BaseAppenderatorDriver.publishInBackground when
invoked via transformAsync in StreamAppenderatorDriver.publish will
cause the resulting future to never complete.
This explains why when encountering https://github.com/apache/druid/issues/9845
the task will never complete, forever waiting for the publishFuture to
register the handoff. As a result, the corresponding "Error while
publishing segments ..." message only gets logged once the index task
times out and is forcefully shutdown when the future is force-cancelled
by the executor.
during segment publishing we do streaming operations on a collection not
safe for concurrent modification. To guarantee correct results we must
also guard any operations on the stream itself.
This may explain the issue seen in https://github.com/apache/druid/issues/9845
