Testing instructions:

1. Create/reuse a WoA site. Use Jetpack Beta to checkout this PR's branch (add/google-analytics-to-mu-wpcom) for "WordPress.com Features".
2. To activate the MU-WPCOM plugin, go to "Settings -> Hosting Configuration", use SFTP or SSH credentials to add the constant to htdocs/wp-config.php: define( 'JETPACK_MU_WPCOM_LOAD_VIA_BETA_PLUGIN', true );

Tests well on my WoA site.

I would approve, but I notice all the wpcomsh auto-formatting changes and it seems like they don't need to be there? They don't look like they'd cause any harm as it's mainly whitespace fixes, but to be safe I wouldn't want to approve without testing all the touched files. Is the intention to keep them in?

[sergeymitr]

@coder-karen thanks for taking a look!
Yeah, those auto-formatted files are confusing.
I managed to revert them so we could deal with it later.

Looks good now, thanks!
