[SPARK-11457][Streaming][YARN] Fix incorrect AM proxy filter conf recovery
from checkpoint
Currently Yarn AM proxy filter configuration is recovered from checkpoint
file when Spark Streaming application is restarted, which will lead to some
unwanted behaviors:
1. Wrong RM address if RM is redeployed from failure.
2. Wrong proxyBase, since app id is updated, old app id for proxyBase is
wrong.
So instead of recovering from checkpoint file, these configurations should
be reloaded each time when app started.
This problem only exists in Yarn cluster mode, for Yarn client mode, these
configurations will be updated with RPC message `AddWebUIFilter`.
Please help to review @tdas @harishreedharan @vanzin , thanks a lot.
