[SPARK-20887][CORE] support alternative keys in ConfigBuilder
## What changes were proposed in this pull request?
`ConfigBuilder` builds `ConfigEntry` which can only read value with one
key, if we wanna change the config name but still keep the old one, it's hard
to do.
This PR introduce `ConfigBuilder.withAlternative`, to support reading
config value with alternative keys. And also rename
`spark.scheduler.listenerbus.eventqueue.size` to
`spark.scheduler.listenerbus.eventqueue.capacity` with this feature, according
to https://github.com/apache/spark/pull/14269#discussion_r118432313
## How was this patch tested?
a new test
