[SPARK-20854][SQL] Extend hint syntax to support expressions
## What changes were proposed in this pull request?
SQL hint syntax:
* support expressions such as strings, numbers, etc. instead of only
identifiers as it is currently.
* support multiple hints, which was missing compared to the DataFrame
syntax.
DataFrame API:
* support any parameters in DataFrame.hint instead of just strings
## How was this patch tested?
Existing tests. New tests in PlanParserSuite. New suite DataFrameHintSuite.
