OffsetSeqMetadata — Metadata of Streaming Batch

OffsetSeqMetadata holds the metadata for the current streaming batch:

Event-time watermark threshold
Batch timestamp (in millis)
Streaming configuration with spark.sql.shuffle.partitions and spark.sql.streaming.stateStore.providerClass Spark properties

Note	`OffsetSeqMetadata` is used mainly when `IncrementalExecution` is created.

OffsetSeqMetadata considers some configuration properties as relevantSQLConfs:

relevantSQLConfs are used when OffsetSeqMetadata is created and is requested to setSessionConf.
