Split modules logic

[elad-pticha]

Module names could be confusing

Imports such as from src.config.config import ... or from src.downloader.downloader import ... could confuse and we should split their logic between multiple files.

For example, we can split the config module into neo4j_config, redis_config, and generic_config.

src -- config ---- neo4j_config ---- redis_config ---- generic_config

Sounds good. Do you think reporter_config is needed as well?
