These options were introduced in 3.19 with support for message signing
and are rather useless, as explained in commit a51983e4dd ("libceph:
add nocephx_sign_messages option"). Deprecate them.
In case there is someone out there with a cluster that lacks support
for MSG_AUTH feature (very unlikely but has to be considered since we
haven't formally raised the bar from argonaut to bobtail yet), make
nocephx_sign_messages also waive MSG_AUTH requirement. This is probably
how it should have been done in the first place -- if we aren't going
to sign, requiring the signing feature makes no sense.
