Deprecation warning

When scaling out, we are seeing:

Deprecated function: array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead in AzureScaleSetProcessor->buildServerServices() (line 96 of /var/aegir/hostmaster-7.x-3.x/sites/all/modules/hosting_webhooks/hosting_webhooks_server/src/CreateServerTrait.php).
