[PATCH 4/8] net_reader: nntp_opt => cfg_opt

[Eric Wong <e@80x24.org>]

Since this our internal NNTP options are keyed by URI section,
there's no need to have separate hashes for NNTP and IMAP
options since they URI already distinguishes them.

This will make future changes to support POP3 and JMAP and
arg caching with lei/store easier.
