Improve logging

[Dinamiko]

Currently logger does not print much useful information, ideally it should display more information about PayPal API requests and responses.

It is important that we do so by not compromising sensible information like access token.

Expected logging entry could look like this:

2021-09-14T10:36:47+00:00 INFO POST https://api.sandbox.paypal.com/some-endpoint
Request Body: {"foo":"bar"}
Response Debug ID: abc123
Response: Array
(
    [code] => 200
    [message] => OK
)
