Support FlintTable batch write

[penghuo]

Description

1. Add FlintWriter in Flint core.
2. Support Batch Write in Spark.

Implementation Detail

FlintTable is capable of batch write operations in overwrite mode. This interacts with the FlintOpenSearchClient within the FlintCore package. During this process, we utilize the CREATE action within the OpenSearch bulk request. Users have the capability to provide an ID field within their options. If no ID is provided, OpenSearch will generate one automatically. When writing to FlintCore, the following conditions are checked:

If a document with the same ID already exists, the system will skip this entry and do nothing.
If no document with the same ID is found, the system will index the new document.

Why not use INDEX action

The INDEX action will delete doc with same id, and index new doc. In case Luncene does not really delete the doc, the storage size is doubled.

Usage Example

val schema = StructType(Seq(StructField("aInt", IntegerType)))
val openSearchOptions = Map("host" -> "localhost", "port" -> "9200", "spark.flint.write.id.name" -> "aInt")
val df = spark.range(15).toDF("aInt")
df.coalesce(1).write.format("flint").options(openSearchOptions).mode("overwrite").save("t002")

To reviewer:
This class is copy from SPARK JacksonGenerator. I did not find easy way to directly use it. You can only review the function i defined
def writeAction(action: String, idOrdinal: Option[Int], row: InternalRow): Unit = {}
