* Upgrade to Lucene 6.4.0
`ValueSource`s are now converted to `DoubleValueSource`s using the Lucene adapter made for the migration to the new API in 6.4.0.
Set lucene version to 6.4.0-snapshot-ec38570 and update all the sha1s/license
Fix invalid combo after upgrade in query_string query. split_on_whitespace=false is disallowed if auto_generate_phrase_queries=true
Adapt the expectations of some tests to the new format of the Lucene explain output
This commit updates JodaTime to version 2.9.5 that contain a fix for a bug when parsing time zones (see https://github.com/JodaOrg/joda-time/pull/332, https://github.com/JodaOrg/joda-time/issues/386 and https://github.com/JodaOrg/joda-time/issues/373).
It also remove the joda-convert dependency that seems to be unused.
closes#20911
Here is the changelog for 2.9.5:
```
Changes in 2.9.5
----------------
- Add Norwegian period translations [#378]
- Add Duration.dividedBy(long,RoundingMode) [#69, #379]
- DateTimeZone data updated to version 2016i
- Fixed bug where clock read twice when comparing two nulls in DateTimeComparator [#404]
- Fixed minor issues with historic time-zone data [#373]
- Fix bug in time-zone binary search [#332, #386]
The fix in v2.9.2 caused problems when the time-zone being parsed
was not the last element in the input string. New approach uses a
different approach to the problem.

- Close buffered reader correctly in zone info compiler [#396]
- Handle locale correctly zone info compiler [#397]

All plugins currently have their own licenses dir for the
dependencyLicenses task, but core disables this and has the check inside
distribution. This may have been better for maven, but for
gradle it makes more sense to just use the dependencyLicenses task that
automatically exists inside :core, and remove the hacked up version that
is inside distribution.
This change creates a proper `distribution` modules in which we have today packaging for
all of our four current packages:
* zip
* tar.gz
* rpm
* deb
Licenes have moved into the distribution project as well. So have the config/ and the bin/ directory
from the core/ project.
The RPM package is now built, if rpmbuild exists.
The bats tests have been moved as well.
Also the zip distribution now executes the REST integration tests.
HDRHistogram has been added as an option in the percentiles and percentile_ranks aggregation. It has one option `number_significant_digits` which controls the accuracy and memory size for the algorithm
Closes#8324
Added a licenses/ directory to core which contains a sha1 file for each JAR
dependency, and one or more LICENSE files and one NOTICE file for each
project.
Also adds dev-tools/src/main/resources/license-check/check_license_and_sha.pl
which checks that the licenses/ dir is up to date during a mvn verify,
and which can be used to update the sha1 files when upgrading dependencies.
