What does this PR do?
APM allows to filter traces / SPANs based on "filters" that can be configured in the datadog.yaml file
https://docs.datadoghq.com/tracing/guide/ignoring_apm_resources/?tab=datadogyaml#trace-agent-configuration-options
Motivation
We need to be able to configure that and the current module version doesn't allow us to do so.
Describe your test plan
If a value (hash) is set for "apm_filter_tags" (via hiera for example), the values will be merged into the datadog configuration hash / yaml file.
