[HIVE-17431] change configuration handling in TezSessionState

Description

The configuration is only set when opening the session; that seems unnecessary - it could be set in the ctor and made final. E.g. when updating the session and localizing new resources we may theoretically open the session with a new config, but we don't update the config and only update the files if the session is already open, which seems to imply that it's ok to not update the config.
In most cases, the session is opened only once or reopened without intending to change the config (e.g. if it times out).
