Default Query Parameters

This PR adds a functionality that allows users to set default query parameters for :index, :update, :create and :delete operations of ElasticSearch/OpenSearch indexes.

One use case is the retry_on_conflict parameter, which can be set to a default value for all update operations. This way, users do not have to specify it every time they perform an update operation.

Example usage:

class UsersIndex < Esse::Index
  request_params(:update) do |_doc|
    { retry_on_conflict: 3 }
  end
end

Or you can define with static value

class UsersIndex < Esse::Index
  request_params(:update, retry_on_conflict: 3)
end

Now when performing an update or bulk update operation on the UsersIndex, the retry_on_conflict parameter will automatically be set to 3 unless overridden.

It will benefit callbacks of esse-async_indexing and esse-active_record gems, as you don't need to define callbacks passing the retry_on_conflict parameter every time.

This functionality is also one step close for the _type removal from the index, as it allows setting the document type for the index without explicit type implementation on this gem. We may use this for routing as well in future
