ifup-post: always update nameserver & search entries in /etc/resolv.conf

2017-10-31T12:11:59+00:00

  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:

ifup-eth: wait for STP to complete setup on bridge if $DELAY is not set

init.d/functions: convert2sec() function added

2017-08-07T11:23:56+00:00

  And network-scripts/network-functions was patched to use convert2sec().

  This function can be used to convert the value of its first parameter
  to a number of seconds - based on the time unit (specified as the
  second parameter).

  This is mostly useful for converting values for use with the sleep(1).

Replace /var/run with /run everywhere
