Extract package `bittorrent-tracker-client`

[josecelano]

Relates to:

• Overhaul clients #669
• Should we merge testing binaries into a single `Tracker Client`? #660

@torrust/torrustaceans had decided to extract all the tracker client functionality into a new package.

packages/
├── clock
├── configuration
├── located-error
├── primitives
├── test-helpers
├── torrent-repository
└── tracker-client (bittorrent-tracker-client) <- the new package

The package will include a lib with the following types:

• UdpClient
• HttpClient

And three binaries (console apps):

• HttpTrackerClient
• UdpTrackerChecker
• TrackerChecker

Those binaries will eventually be merged into a single console app with three subcommands.

Hi @da2ce7, I think the lib should be called bittorrent-tracker-client, but maybe the console app should be called torrust-tracker-client instead. What do you think?

Clients in the lib are generic, but the console client is just one more Torrust app.
