Refactors SimpleQueryStringBuilder/Parser
This commit makes SimpleQueryStringBuilder streamable, add hashCode and equals. Adds a dedicated builder/parser unit test, fixes formatting, adds JavaDoc where needed, adjust the handling of default values according to https://github.com/elastic/dev/blob/master/design/queries/general-guidelines.md Switched to using toLanguageTag/forLanguageTag when parsing Locales. Using LocaleUtils from either Elasticsearch or Apache commons resulted in Locales not passing the roundtrip test. For more info see https://issues.apache.org/jira/browse/LUCENE-4021 Relates to #10217
