drush doesn't appear to pull the correct settings for multisite on drupal 8

[srees]

I've installed the latest master of drush with drupal 8 on Ubuntu 14. Everything seems to be running except for having an issue with drush and multisite.

If I run, for example, 'drush cr' from inside the sites/site4 folder, I get an error
"Missing $settings['hash_salt'] in settings.php"
However, it is set for that site. It's as if it's trying to read the default settings.php, which we aren't using.

Even if I specify -l and the site name/url, it doesn't respect the site specification and pulls from default.

If I symlink the correct settings.php file to the default folder, it works.

Perhaps related to #857 ?

Likely caused the bootstrap level changed by @jonhattan in d809c2d . Ok to revert to CONFIGURATION level?

Updated to DRUSH_BOOTSTRAP_DRUPAL_SITE. We must avoid any call to drupal_bootstrap() in D8 because it ends up in a full bootstrap.
