ifup-post: always update nameserver & search entries in /etc/resolv.conf
This is complete rework of how we generate the /etc/resolv.conf.
Fixes:
* always update 'nameserver' & 'search' entries when DNS* & DOMAIN
options (respectively) were updated in ifcfg-* files
* always update the order of 'nameserver' entries when the order of
DNS* options was updated
* always keep /etc/resolv.conf.save as a proper backup - do not
overwrite it everytime when updating 'nameserver' or 'search'
Enhancements:
* added support for DNS3 option (equals to MAXNS value in GLIBC)
* added logic to process duplicate DNS* options
* added logic to process randomly omitted DNS* options (e.g. omitting
DNS1 while specifying DNS2 and/or DNS3 will still work now)
This work was based on these two RHEL-7.5 BZs:
