significant terms aggregation missing regex include method

[tatarco]

Hello,
by documentation of SignificantTermsAggregation should support regex aggregation
Documentation

The object new TermsAggregation.Builder() is missing the include method that supports it
it only has
public final Builder include(String value) when for exclude the currect implemtation exists (TermsExclude exclude)

it's expected that the object will have
private final TermsInclude include;
as in TermsAggregation.Builder

not having it causes the wrong behavior and elastic to not use regex for filtering

This is a problem in the API specification used to produce the Java code: an issue has been opened at elastic/elasticsearch-specification#1553

Once the API spec has been fixed, this issue will be resolved in the next minor release.

Java code has been updated, this is included in 7.17.3 and will be in the upcoming 8.2.0.
