Refactor dimensiondata_network module (#21043)

Browse source 
* Refactor dimensiondata_network to use shared base class for common functionality.

* Experiment: remove the assignments in the "except ImportError:" block that keep PyCharm happy. If this fixes the build, then I reckon there's a bug in the validate-modules script (https://github.com/ansible/ansible/blob/devel/test/sanity/validate-modules/validate-modules#L322).

* Remove unused imports.

* Changes based on feedback from @gundalow for ansible/ansible#21043.

- Use no_log=True for mcp_password parameter.
- Collapse module parameter definitions.

* Use shared definitions and doc fragments for common module arguments (ansible/ansible#21043).

* Make default network plan "ESSENTIALS", rather than "ADVANCED" (this is consistent with our other tooling).
Tidy up module parameter documentation.

* Simplify dimensiondata module documentation fragments (didn't know you could include multiple fragments).

* Change 'verify_ssl_cert' module parameter to 'validate_certs'.
