Impossible to set wr.config.distributed

[kukushking]

Describe the bug

It's currently impossible to set distributed flag to False using config if ray and modin are installed, e.g:

import awswrangler as wr

wr.config.distributed=False

wr.read_parquet(...)

This happens because ray.init runs on package import thus the only way to disable distributed code is to set an environment variable prior to the import.

Expected behavior

We should provide an ability to disable distributed using wrangler config class.

Possible solution

One possibility to explore is to do lazy ray.init when application code runs a function that requires distributed functionality
