libceph: deprecate [no]cephx_require_signatures options
These options were introduced in 3.19 with support for message signing and are rather useless, as explained in commit a51983e4dd2d ("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.
