Before this fix, IPv6 addresses would not be parsed correctly after evaluating host/hosts for placeholders. With this fix, IPv6 addresses are correctly parsed.

Description of problem:
Forwarding logs to external ipv6 elasticsearch instance fails when using fluentd as log collector. Collector pods stream below logs:
2023-06-29 16:55:05 +0000 [warn]: [elasticsearch_secure] failed to flush the buffer. retry_times=5 next_retry_time=2023-06-29 16:55:35 +0000 chunk="5ff478dd6b35c5b24fccf3c705fc07e2" error_class=Fluent::Plugin::ElasticsearchOutput::RecoverableRequestFailure error="could not push logs to Elasticsearch cluster (\{:host=>nil, :port=>nil, :scheme=>\"fd00\", :user=>\"elastic\", :password=>\"obfuscated\"}): no implicit conversion of nil into String" 2023-06-29 16:55:05 +0000 [warn]: suppressed same stacktrace 2023-06-29 16:55:35 +0000 [warn]: [elasticsearch_secure] failed to flush the buffer. retry_times=6 next_retry_time=2023-06-29 16:56:34 +0000 chunk="5ff478dd6b35c5b24fccf3c705fc07e2" error_class=Fluent::Plugin::ElasticsearchOutput::RecoverableRequestFailure error="could not push logs to Elasticsearch cluster (\{:host=>nil, :port=>nil, :scheme=>\"fd00\", :user=>\"elastic\", :password=>\"obfuscated\"}): no implicit conversion of nil into String" 2023-06-29 16:55:35 +0000 [warn]: suppressed same stacktrace

All Red Hat OpeShift Logging Operator Versions
How reproducible:
100%
Steps to Reproduce:
- Create a ipv6 RHOCP cluster (singlestack will be ok here)
- Install Red Hat OpenShift Logging Operator.
- Setup a virtual machine which has ipv6 and has elasticsearch up and running (setup this instance in the same network where RHOCP was running to reduce the infra complexity)
- Configure CLF on RHOCP cluster to send logs to this externally hosted elasticsearch instance.
Actual results:
The logs are not forwarded to external elasticsearch instance and collector pods stream below error:
2023-06-29 16:55:05 +0000 [warn]: [elasticsearch_secure] failed to flush the buffer. retry_times=5 next_retry_time=2023-06-29 16:55:35 +0000 chunk="5ff478dd6b35c5b24fccf3c705fc07e2" error_class=Fluent::Plugin::ElasticsearchOutput::RecoverableRequestFailure error="could not push logs to Elasticsearch cluster (\{:host=>nil, :port=>nil, :scheme=>\"fd00\", :user=>\"elastic\", :password=>\"obfuscated\"}): no implicit conversion of nil into String"
Expected results:
The logs should flow normally to external elasticsearch instance.
Additional info:
Curl request from collector pods is completed successfully. See below:
- curl -u elastic --cacert /var/run/ocp-collector/secrets/es-secret/ca-bundle.crt [https://[IPv6]:|https://[ipv6]/]<Port>
