Summary of Changes

On the CLI, we can check for updates of the core and we can run the update as well, but we actually don't know what we are updating to, what update channel we are on and what the update process is actually doing right now. This PR tries to fix some of the issues by allowing to manage the update channels.

By calling php cli/joomla.php core:update:channel, you get the update channel the site is currently on. By adding the parameter default, next, testing or custom, you can set the update channel to that respective one. For custom you need to also add the --url=<url> parameter for the custom URL.

Testing Instructions

1. Run php cli/joomla.php core:update:channel to display the currently configured update channel.
2. Run php cli/joomla.php core:update:channel next to set it to the "next" update channel. Check that the params column in #__extensions for the com_joomlaupdate row contains the updated updatesource value and that location column for Joomla! Core in #__update_sites contains https://update.joomla.org/core/sts/list_sts.xml as URL.
3. Run it in addition with other combinations of options and see the change reflected in the core tables.
4. Run php cli/joomla.php core:check-updates to check for updates from the new update source.
