[hiredis_ssl] Add support for skipping certificate verification

[sewenew]

redis-cli 6.2 already supports skipping certificate verification and setting default verification path: #8416. However, it seems that hiredis_ssl doesn't catch up with this feature.

Is there a plan to port this feature to hiredis_ssl? Thanks!
