make conan config get return the real configuration to be used

[memsharded]

From

• fix storage path #5350
• Possible "conan config get storage.path" regression #5338

conan config get returns the raw values from the conan.conf file. This might be totally useless, or even wrong, because if there are env-vars defined, as CONAN_STORAGE_PATH, then the value returned by conan config get storage.path will be the one in the file, but not the one really applied in the configuration when running conan.

#5350 fixes this for storage.path only:

• Check if this should be extended for other fields, like cacert_path, or non_interactive
• Investigate what makes sense for conan config set. Probably it should warn (at least) if the env-var is set, because the value set won't be used either.
• Investigate what to do with sections: conan config get storage will return path = ./data, without resolving the data as conan config get storage.path

Closing, as Conan 2.0 does not provide conan config get
