Fix for : (1). Hive service check for HSI and (2). HSI alert on wire encrypted cluster

*Current/Problem :* SSL custom configs 'hive.server2.keystore.path' and 'hive.server2.keystore.password' are currently read from hive1/hive-site. If a user had added it separately in Hive2/hive-interactive-site, we have a problem that we are not reading it from Hive2/hive-interactive-site.
