s3-passdb: Rename pdb_samba4 to samba_dsdb and autoconfigure when we are a AD DC

The name samba_dsdb is not ideal, but it matches the primary ldb
module we use, and more importantly it avoids having '4' in the name.
We should slowly avoid using the term samba4 in long-term places like
the smb.conf because it is confusing to users given we are shipping
Samba 4.0 as an AD DC as well as all the other supported roles (domain
member/standalone server/classic DC)

Additionally, samba4 will be an odd name when we eventually release
Samba 5.0!

samba4 remains accepted as an alias to ensure existing smb.conf files
load, but to allow changes here in the future, we set the value during
the smb.conf load, and not during the provision when we are an AD DC.

This simplifies the default smb.conf for the vast majority of our
users and reduces the number of things listed in smb.conf files that
we later have to work around if we wish to change the
name/implementation of the passdb glue module again.
