[SPARK-19058][SQL] fix partition related behaviors with
DataFrameWriter.saveAsTable
## What changes were proposed in this pull request?
When we append data to a partitioned table with
`DataFrameWriter.saveAsTable`, there are 2 issues:
1. doesn't work when the partition has custom location.
2. will recover all partitions
This PR fixes them by moving the special partition handling code from
`DataSourceAnalysis` to `InsertIntoHadoopFsRelationCommand`, so that the
`DataFrameWriter.saveAsTable` code path can also benefit from it.
## How was this patch tested?
newly added regression tests
