Do not error when include clause doesn't match any file
Steps to reproduce
mkdir /etc/knot/conf.dfor future configuration files.
include: "/etc/knot/conf.d/*.conf"in knot.conf.
- Start knot.
knotd: 2018-03-26T21:47:17 error: config, file '/etc/knot/knot.conf', line 12, item 'include', value '/etc/knot/conf.d/*.conf' (file error) knotd: critical: failed to load configuration file '/etc/knot/knot.conf' (file error) knotd: 2018-03-26T21:47:17 critical: failed to load configuration file '/etc/knot/knot.conf
I regularly use nginx and I know it handles this. Apache apparently has an
IncludeOptional clause for this.
I have a patch to always make it optional. I can have a look to add another clause if necessary.
(Also I can't create forks on this instance atm?)
