[SPARK-15804][SQL]Include metadata in the toStructType
## What changes were proposed in this pull request?
The help function 'toStructType' in the AttributeSeq class doesn't include
the metadata when it builds the StructField, so it causes this reported problem
https://issues.apache.org/jira/browse/SPARK-15804?jql=project%20%3D%20SPARK
when spark writes the the dataframe with the metadata to the parquet
datasource.
The code path is when spark writes the dataframe to the parquet datasource
through the InsertIntoHadoopFsRelationCommand, spark will build the
WriteRelation container, and it will call the help function 'toStructType' to
create StructType which contains StructField, it should include the metadata
there, otherwise, we will lost the user provide metadata.
## How was this patch tested?
added test case in ParquetQuerySuite.scala
(If this patch involves UI changes, please attach a screenshot; otherwise,
remove this)
