[RELEASE] Version 29.5.0

[sergio-bobillier]

In this release:

Fixed

• A NameError that was being raised when jay_api/elasticsearch/client was
  required without requiring elasticsearch.
• A NoMethodError that was being raised by Elasticsearch::Stats::Indices
  when active_support/core_ext/string hadn't been loaded.

Added

• The #force_merge method to the Elasticsearch::Index class. This method
  starts a Forced Segment Merge on the index.
• The #totals method to Elasticsearch::Stats::Index, this gives the caller
  access to the index's total metrics.
• The Elasticsearch::Stats::Index::Totals class. The class contains information
  about an index's total metrics, for example, total number of documents, total
  size, etc.
• The #settings method to the Elasticsearch::Index class. This gives the
  caller access to the index's settings.
• The Elasticsearch::Indices::Settings::Blocks class. The class encapsulates
  an index's blocks settings (for example, whether the index is read-only).
• The Elasticsearch::Indices::Settings class. The class encapsulates an
  index's settings.
• It is now possible to configure the type used by the RSpec::TestDataCollector
  class when pushing documents to Elasticsearch. If no type is specified in the
  configuration the default type will be used.
• Allow the Elasticsearch::Index and Elasticsearch::Indexes's #push method
  to receive a type parameter, just like #index does.
