Add sshPublicKeyAttribute attribute setting for ldap auth，and Allow setting labels and annotations for gitea pvc. (#76)

1. sshPublicKeyAttribute is useful to sync ssh public keys from ldap.
2. It would be easier to set pvc annotations/labels for those who are using storage services from cloud providers.
