This patch implements lazy loading of the JSON data.
Motivation: in most requests not all JSON data is needed, but loaded. By
example these four JSON files:
- currencies.json ~550KB
- engine_descriptions.json ~1,3MB
- external_bangs.json ~1,3MB
- osm_keys_tags.json ~ 2,2MB
most often not used and consume a lot of memory and BTW they also extend the
time required to instantiate a walker.

In the past, some files were tested with the standard profile, others with a
profile in which most of the messages were switched off ... some files were not
checked at all.
- ``PYLINT_SEARXNG_DISABLE_OPTION`` has been abolished
- the distinction ``# lint: pylint`` is no longer necessary
- the pylint tasks have been reduced from three to two
1. ./searx/engines -> lint engines with additional builtins
2. ./searx ./searxng_extra ./tests -> lint all other python files
