Revert "Make https cert checking dependent on https checking to reduce emails"

Unfortunately this does not work as if any cert check fails on any https server it stops checking https on all https servers which is not what I wanted.

This reverts commit 0189a8938d40d2a296bf7f9e5ae9de2cf402253d.
Make https cert checking dependent on https checking to reduce emails

Malcolm Scott told me that if I removed dependent_hostgroup_name it would work as intended.
