[SPARK-14422][SQL] Improve handling of optional configs in SQLConf
## What changes were proposed in this pull request?
Create a new API for handling Optional Configs in SQLConf.
Right now `getConf` for `OptionalConfigEntry[T]` returns value of type `T`,
if doesn't exist throws an exception. Add new method
`getOptionalConf`(suggestions on naming) which will now returns value of type
`Option[T]`(so if doesn't exist it returns `None`).
## How was this patch tested?
Add test and ran tests locally.
