[SPARK-15681][core] allow lowercase or mixed case log level string when
calling sc.setLogLevel
## What changes were proposed in this pull request?
Currently `SparkContext API setLogLevel(level: String) `can not handle
lower case or mixed case input string. But `org.apache.log4j.Level.toLevel` can
take lowercase or mixed case.
Also `resetLogLevel` to original configuration could be helpful for users
to switch log level for different diagnostic purposes.
## How was this patch tested?
A unit testcase is added.
