Packer: Remove authorized_keys
Packer: Remove access_key and secret_key. We can use environment variables.
Default JETPACK_DEV_DEBUG true for public servers

On public servers, we can presumably use things like Photon.

see #361
Set SUBDOMAIN_INSTALL true on new public servers.

Presumably, you have to configure the DNS for a staging server anyway
so we might as well use subdomains from the start here.
Vagrant: Change the owner of the shared folder to www-data

Fixes #362
Fix JETPACK_DEV_DEBUG

The logic was reversed. It should be enabled in Vagrant on nowhere else.
Move apt-get upgrade to main section

We don't really need this to run before everything else,
so there's no reason to force it to.
Make wp-content group writable

Fixes #364
Also set proper ownership of wp-content directory

See #364
Bump puppet-wp version
Make sure the necessary directories in wp-content have group write
permission.

See #364
We don't need to ignore wp-cli, we moved it inside the VM.
Add .gitignore specific to www directory.

This will be useful when/if we decide to split the www directory to
its own repo.
Ensure vip themes repo exists
Set WP_DEBUG and JETPACK_DEV_DEBUG true.

The www-data user doesn't have access to environment varaibles,
so the getenv call always returns true.
Set JETPACK_DEV_DEBUG in local config.
Set owner of shared files to www-data:www-data.

Otherwise every provision tries to change the owner of them all.
Set dmode=775, fmode=664 in Vagrant

Like b58f746618c9913baca4c7ec226b44be1f8b0114, we should match what
is happening in Puppet so every file doesn't have to be updated on
every provision.
Merge branch 'master' into dashboard
