Shuhei Matsumoto ad323b8064 iscsi&scrpts/rpc: Require to specify CHAP secret file explicitly to load it 
Previous patches enabled users to configure CHAP secrets dynamically
by RPCs. Subsequent patches will enable users to load CHAP secrets
from JSON config file.

Loading CHAP secret file is done by default and this will conflict to
JSON config file.

Hence the path to CHAP secret file is required to specify in the config
file or JSON RPC set_iscsi_options explicitly after this patch.

Users who have used CHAP secret file are expected to specify it explicitly
and this will be no harm for them.

Besides, CHAP secret file is not oly for discovery sessions but also for
login to iSCSI targets. However there were wrong description to make user
misunderstand. Hence remove these wrong description in this patch too.
