Refactoring: BandwidthCommunity may be removed.

[drew2a]

We still have issues related to the BandwidthCommunity which causes the Tribler crashes.
At the same time, the BandwidthCommunity functionality has not been used for at least a couple of years.

It looks like a big piece of code that could be safely removed.

Sentry issue: TRIBLER-16Q

This should be repaired for MeritRank. Please fix the stability issues. For long term lab progress we need a reputation graph.

Sentry issue: TRIBLER-171

[drew2a]

The error continues to occur in BandwidthCommunity. See the latest: https://sentry.tribler.org/organizations/tribler/issues/2548/.

Should we continue trying to fix them, or should we remove the entire feature as it will eventually be replaced in favor of MeritRank?

Indeed, we might as well delete it all now. This commit from 3 weeks ago deleted a lot.
Then @InvictusRMC and @grimadas can start with a somewhat clean start with MeritRank deployment.
