Improve debug logging

[m-horky]

This change clearly labels each section that's printed to make it easier to identify the interesting parts.

This also adds SUBMAN_DEBUG_PRINT_TRACEBACKS flag to print the traceback directly to stdout.

Example:

(the white horizontal line is just result of putting two screenshots together, the traceback was too long)

[m-horky]

Set to draft; src/cloud_what/_base_provider.py needs updating as well.

[m-horky]

Question for the reviewer: would it be worth to define the colors on a single place? This code isn't updated often, and it is quite isolated, so maybe it is enough, as it has been for several years now.

[jirihnidek]

Yeah, I would define colors on single place. Maybe it could be useful for other parts of code. We could make output of subscription-manager more colorful.

[jirihnidek]

If you are significantly changing debug printing, then please print request_type first to get something like this:

Request:
GET https://centos8-candlepin:8443/candlepin/ (using consumer auth)

[m-horky]

Thanks. You are right, I discovered I even made local changes that did that, I forgot to finish it.

This is how it looks like now:

[jirihnidek]

LGTM, Thanks for updates 👍
