SOURCE_DIR only applies to source plugins, not filter plugins

Bug Summary

When developing filter plugins, passing --source-dir does not allow for local filter plugins, only local local source plugins. This means that the filter plugin has to be published in a collection to be tested.

Environment

[root@dd6d2c871e07 cloin.eda]# ansible-rulebook --version
__version__ = '1.0.1'
  Executable location = /usr/local/bin/ansible-rulebook
  Drools_jpy version = 0.3.4
  Java home = /usr/lib/jvm/jre-17-openjdk
  Java version = 17.0.8
  Python version = 3.11.4 (main, Jun  7 2023, 00:00:00) [GCC 13.1.1 20230511 (Red Hat 13.1.1-2)]

Steps to reproduce

• Create a filter plugin and keep it local.
• Specify the filter plugin in a rulebook against an already published event source:

---
- name: Respond to webhook POST
  hosts: all
  sources:
    - ansible.eda.webhook:
        host: 0.0.0.0
        port: 5000
      filters:
        - endpoint_as_namespace:

• Run ansible-rulebook
  • ansible-rulebook -r webhook.yml -i inventory.yml -S ./extensions/eda/plugins/event_filter/ --verbose

Actual results

ansible-rulebook fails because it can't find the filter plugin

Expected results

ansible-rulebook finds the filter plugin based on the path in SOURCE_DIR

I would say is not a bug but a feature request. sources flag indicates clearly that are sources, not filters. Anyway the description could be better.

I guess we could add a new flag for local filters or create a new one "plugins" able to take both types.

[cloin]

Should I open a new issue with a better description?

If you agree to treat it as a request feature that looks good to me.
