Upgrade to phpcr-odm 2.0

Support jackalope 2.0

Replace doctrine cache with PSR-6 cache with the symfony/cache implementation. The configuration of metadata_cache_driver changed. By default, it creates an array cache. To configure a service, specify type: service and specify your service in the id property. To use a cache pool, specify the service id of that pool.

Introduced the ManagerRegistryInterface for the ManagerRegistry and adjusted the service alias for autowiring to the interface.

The following container parameters are no longer taken into account (memcache and apc seem to have never been used anyways). If you have customised the array cache class, please check if this is still needed - and note that starting from this version, PSR-16 simple cache is used:

doctrine_phpcr.odm.cache.array.class doctrine_phpcr.odm.cache.apc.class doctrine_phpcr.odm.cache.memcache.class doctrine_phpcr.odm.cache.memcache_host doctrine_phpcr.odm.cache.memcache_port doctrine_phpcr.odm.cache.memcache_instance.class doctrine_phpcr.odm.cache.memcached.class doctrine_phpcr.odm.cache.memcached_host doctrine_phpcr.odm.cache.memcached_port doctrine_phpcr.odm.cache.memcached_instance.class doctrine_phpcr.odm.cache.xcache.class

If no username is defined for a session, and if you use Jackalope >= 2.0, the credentials service for this session is no longer created and null is passed as credentials.
