This commit adds the skeleton for an issue transfer command.
Almost all of the functionality is implemented, but it is missing
the actual transfer of issues. I'm nervous about testing this, so
I'm going to implement the rest of the functionality first.
This contains the basic framework for our new `monorepo-merge`
command. The goal will be for this command to handle the heavy lifting
for merging repositories with full history. It will (ideally) bring any
plugin or package into the repository in a ready-to-use state.
Fixes a PHP Fatal error:
```
PHP Fatal error: Uncaught Error: Class 'Automattic\WooCommerce\MonorepoTools\Changelogger\DateTime' not found in /var/www/woo/wp-content/plugins/woocommerce/tools/changelogger/Formatter.php:143
```
* Removed Changlogger Autoload
* Changed Jetpack Changelogger Formatter Loading
Rather than using the Composer autoload, we should use the
changelogger's "filename" option to point directly at the file.
This keeps the file out of the autoloads, since it's possible that
plugins or packages may be symlinked and break the relative
path to the plugin.
