Enable security for Drill HiveStoragePlugin based on a config parameter

For enabling security on DrillClient to Drillbit and Drillbit to Drillbit channel we have a configuration. But this doesn't ensure that Storage Plugin channel is also configured with security turned on. For example: When security is enabled on Drill side then HiveStoragePlugin which Drill uses doesn't open secure channel to HiveMetastore by default unless someone manually change the HiveStoragePluginConfig.

With this JIRA we are introducing a new config option
security.storage_plugin.enabled: false based on which Drill can update the StoragePlugin config's to enable/disable security. When this config is set to true/false then for now Drill will update the HiveStoragePlugin config to set the value of hive.metastore.sasl.enabled as true/false. So that when Drill connects to Metastore it does so in secured way. But if an user tries to update the config later which is opposite of what the Drill config says then we will log a warning before updating.
Later the same login can be extended for all the other storage plugin's as well to do respective setting change based on the configuration on Drill side.
