acquia_connector 8.x-2.0-rc1

This release includes an update hook that moves some configuration into the state system. Be sure to run update.php and re-export your configuration (if you are using configuration management).

• Added Drupal 9 compatibility (removed deprecated service calls and declared module D9-compatible): #3113571: Connector uses deprecated path alias service
• Fixed invalid config schema: #2983641: Invalid config schema
• Moved subscription and SPI data out of config and into the state system: #2864697: Move subscription and SPI data out of config and into state API
• Removed usage of md5 hashes, which were flagged by static analysis tools as a security risk (though they weren't being used in a sensitive way): #3105541: Weak algorithms usage should be avoided
• Fixed unnecessary invalidation of cache tags during subscription updates #3105440: Acquia Connector's calling Subscription::update() sometimes invalidates cache tags unnecessarily
• Removed hook_acquia_subscription_status() since it is no longer used anywhere.
