Adapt the cp2k parsers to the new aiida-cp2k package.

[yakutovicha]

This PR removes the copy-pasted BaseCp2kParser with the parser imported from the aiida-cp2k plugin. Due to the changes introduced recently in https://github.com/aiidateam/aiida-cp2k/pull/84, the multistage workflow woudn't work correctly with the latest version of the cp2k plugin.

To be honest I've no idea why docs are not building. The aiida-cp2k package is installed, but there is sitll a complaint:

/home/runner/work/aiida-lsmo/aiida-lsmo/aiida_lsmo/parsers/__init__.py:docstring of aiida_lsmo.parsers.Cp2kAdvancedParser:1:py:class reference target not found: aiida_cp2k.parsers.Cp2kBaseParser

The documentation is not working on my computer too, after pulling your PR branch:

I tested:

• run_BindingSiteWorkChain_MOF74_CO2.py (need a fix that I will push to develop)
• run_multistage_h2o.py

And they run fine: please merge after fixing the documentation.

I'm also not quite sure where exactly it comes from, but you can either add the missing reference to the nitpick exceptions: https://github.com/lsmo-epfl/aiida-lsmo/blob/develop/docs/source/conf.py#L73

or add aiida_cp2k to intersphinx https://github.com/lsmo-epfl/aiida-lsmo/blob/develop/docs/source/conf.py#L70

Thanks Leo, it worked!
