update pylintrc file: generate minimal version from existing configuration

[thehrh]

You might have noticed the many warnings emitted when running pylint. These are due to PISA's current pylintrc file, the last changes to which were made nearly seven years ago. At the time, Pylint 2.2.2 was the most recent release, whereas Pylint 4.0.4 was released a couple of weeks ago. The file was originally generated in 83e2832, possibly with Pylint 1.7, and only underwent three minor changes.

As a result, we are

• specifying options that aren't recognised any longer:

E0015: Unrecognized option found: optimize-ast, files-output, no-space-check, bad-functions, function-name-hint, variable-name-hint, const-name-hint, attr-name-hint, argument-name-hint, class-attribute-name-hint, inlinevar-name-hint, class-name-hint, module-name-hint, method-name-hint (unrecognized-option)

• "useless" option values (no list provided here, but all warnings but one refer to Remove the python3 porting mode from the codebase pylint-dev/pylint#4942, and the last, about removal of C0330, to Remove bad continuation from the codebase pylint-dev/pylint#3571) ,
• and unknown option values:

W0012: Unknown option value for '--enable', expected a valid pylint message and got 'old-octal-literal' (unknown-option-value)
W0012: Unknown option value for '--enable', expected a valid pylint message and got 'old-ne-operator' (unknown-option-value)
W0012: Unknown option value for '--enable', expected a valid pylint message and got 'long-suffix' (unknown-option-value)

The new pylintrc in this PR accounts for all the changes to Pylint's configuration options, and has been condensed down to a minimal version, containing only PISA's non-default option values. I produced it by generating a new file from the existing configuration with Pylint 4.0.4 (pylint --generate-rcfile > <filename>), a new file with defaults only (pylint --rcfile="" --generate-rcfile > <filename2>), and comparing the two.

• I still need to check whether there are any recent equivalent settings that I need to specify to replace the old unrecognised ones. If this turns out to be too much of an effort, I'd suggest to just ignore them and live with the fact that we've lost certain non-default configuration options.

• Also, I want to check which minimum Pylint version we should now require in setup.py

Below are the results of some quick research on the 14 unrecognised options. Their functionality does not seem to be implemented any longer and I doubt anyone here cares about them.

• optimize-ast (was: no): removed in https://pylint.readthedocs.io/en/latest/whatsnew/1/1.7/summary.html#removed-changes
• files-output (was: no): also removed in https://pylint.readthedocs.io/en/latest/whatsnew/1/1.7/summary.html#removed-changes
• no-space-check (was: trailing-comma,dict-separator): removed in https://pylint.readthedocs.io/en/latest/whatsnew/2/2.6/summary.html#other-changes
• bad-functions (was: map,filter,input): unclear when removed (Incompatible config file options for naming hints in pylint 2.14.0 pylint-dev/pylint#6931)
• function-name-hint, variable-name-hint, const-name-hint, attr-name-hint, argument-name-hint, class-attribute-name-hint, inlinevar-name-hint, class-name-hint, module-name-hint, method-name-hint: apparently removed in 1.8 (Incompatible config file options for naming hints in pylint 2.14.0 pylint-dev/pylint#6931)

Concerning the minimum version, the last version below 3.0 does not recognise "use-implicit-booleaness-not-comparison-to-string" and "use-implicit-booleaness-not-comparison-to-zero" option values for the "disable" option. Versions >= 3.0 do not seem to be troubled by the new pylintrc. There is probably no harm in requiring the latest release version though, let's see.

Local develop install was successful (got python 3.10.19 and pylint 4.0.4)

Finally, concerning the three unknown option values (W0012) above, they all seem to have been relevant during a Python 2 -> 3 transition, so there's nothing to do with respect to those either.
