feat(helm): add tpl support for pattern_ingester and ingester_client

[paulojmdias]

What this PR does / why we need it:

Which issue(s) this PR fixes:
Fixes #15464
Fixes #12054
Fixes #18652

Special notes for your reviewer:

• The code from ingester_client comes from feat(helm): Add missing server config ingester_client #12054 and seems abandoned.
• Change for pattern_ingester does not break any current deployment.
• Added support for compactor_grpc_client configuration

Checklist

• Reviewed the CONTRIBUTING.md guide (required)
• Documentation added
• Tests updated
• Title matches the required conventional commits format, see here
  • Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
• Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
• If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR

Could you please add #12054 and #18652 to the list of fixed issues? that would close the duplicate PR on merge.

@jkroepke done, please review 🙌

I also rebased the branch and updated the last CHANGELOG.md entry which has the PR reference missing.
