Steve Wilkerson 09939a04de Move fluentbit and fluentd configs to values.yaml
Defines configuration files for fluentbit and fluentd via the
values.yaml file for fluent-logging. This provides flexibility in
defining parsers and routes for log gathering and routing

This functionality is added via helm-toolkit helper functions for
both fluentd and fluentbit to make the values configuration
cleaner
