Cherry-pick: elastic#10030 and elastic#9869 to 6.5: Handle IPv6 zone …

…id in IIS filebeat ingest pipeline (elastic#10057)

IIS logs can include zone ids when using IPv6, this is correctly parsed
but geoip processor doesn't accept these addresses. Create a temporary
field without the zone id to be used by geoip processor.

(cherry picked from commit d59ae8c)
(cherry picked from commit 5f1f6ca)
(cherry picked from commit e05f967)
