v0.6.0

Changes in APIs:

• Updated source code documentation, updated rubydocs.
• async_search.status - Adds keep_alive Time parameter. Specifies how long the async search needs to be available. Ongoing async searches and any saved search results are deleted after this period. Server default: 5d.
• async_search.submit - Removes min_compatible_shared_node and scroll parameters.
• cat.aliases, cat.count, cat.help, cat.indices, cat.ml_data_frame_analytics, cat.ml_datafeeds, cat.ml_jobs, cat.ml_trained_models, cat.transforms, indices.exists_alias, indices.get_alias - Removes local parameter (not applicable).
• Inference APIs promoted from Experimental to stable: inference.delete, inference.get, inference.inference, inference.put.
• open_point_in_time adds allow_partial_search_results boolean parameter. If false, creating a point in time request when a shard is missing or unavailable will throw an exception. If true, the point in time will contain all the shards that are available at the time of the request.
• search - Removes min_compatible_shard_node parameter (not applicable).
