Joona Hoikkala c08a4dec2d Refactor augeas_configurator.py functionality to configurator.py and parser.py accordingly. (#7181)
This pull request moves the functionality within `AugeasConfigurator` that previously existed as a parent class of `ApacheConfigurator` to `ApacheConfigurator` and `ApacheParser` accordingly.

Most of the methods were moved as-is, and one (`recovery_routine()`) was completely removed. Few of the methods had to be split between the configurator and parser, good example of this is `save()`.

The Augeas object now lives completely within the `ApacheParser`.

* Remove augeasconfigurator

* Fix references

* Adjust tests accordingly

* Simplify test

* Address review comments

* Address review comments

* Move test_recovery_routine_reload
