[python-pytrakt] Privacy: Don't log headers to protect privacy

[glensc]

Scenario, where need to really debug HTTP headers, are perhaps when developing this library. This is never useful for end-users and could cause leaking the tokens when sharing logs:

refs:

• watch doesn't add to history anymore Taxel/PlexTraktSync#758 (comment)

maybe add a switch in config which is deactivated by default.

It is sometimes useful to the user when working with multiple instances to check for cross-contamination of config.

[glensc]

this project doesn't support instances, at least not in v3

[glensc]

Here's are more examples where user shared their tokens just because they didn't know:

• Sync Stops Mid-Run Taxel/PlexTraktSync#805 (comment)
• Plextraktsync crashes right after sync starts Taxel/PlexTraktSync#886 (comment)
