Move packages into a subdirectory in the cache directory

[bradyvercher]

Packages are currently cached in the top level of the cache path defined in the service provider, so the directory structure looks something like this:

├─ wp-content
   └─ uploads
      └─ satispress-xxxx
         └─ akismet
            └─ akismet-4.0.8.zip

That doesn't really allow for adding anything else in that same location that needs to be stored on the filesystem, so I'm thinking packages should be moved to a /packages subdirectory:

├─ wp-content
   └─ uploads
      └─ satispress-xxxx
         ├─ cache
         ├─ logs
         ├─ packages
         │  └─ akismet
         │     └─ akismet-4.0.8.zip
         └─ .htaccess

Why not:

├─ wp-content
   ├─ satispress[-xxxx]
   │     ├─ cache
   │     └─ logs
   └─ uploads
      └─ satispress-xxxx
         ├─ akismet
         │  └─ akismet-4.0.8.zip
         └─ .htaccess

cache/ and logs/ are nothing to do with Uploads.

The /uploads directory is usually the only location that's reliably writable on most servers and it's pretty standard for plugins to use it for data that's stored on the filesystem. Most backup plugins use it as does WooCommerce for logs.

It's also usually configured to be excluded from VCS repos and symlinked during deployments, so using something directly in /wp-content might cause issues.
