The LDAP connection can also timeout when trying to join a Windows DC
with a very large database. However, in this case Windows gives a
slightly different error message (NT_STATUS_CONNECTION_RESET instead of
NT_STATUS_CONNECTION_DISCONNECTED).

Currently the online/rename backup files always use the default backend
(TDB) and there is no way to change this.
This patch adds the backend-store option to the backup commands so that
you can create a backup with an MDB backend, if needed.

Joining a large DB can take so long that the LDAP connection times out.
The previous patch fixed the 'happy case' where the join succeeds.
However, if the commit or replication fails (throwing an exception),
then the cleanup code can also fail when it tries to delete objects from
the remote DC. This then gives you an error pointing to
cleanup_old_accounts() rather than what actually went wrong.
This patch adds a sanity-check that if the join fails, that the LDB
connection to the remote DC is still alive, before we start deleting
objects.

When joining a very large domain (e.g. 100K users), the replication can
take so long that the LDAP connection to the remote DC times out.
This patch avoids the problem by adding in a sanity-check after the
replication finishes that the LDB connection is still alive. If not,
then we reconnect.

When a new DC is joined to the domain, samba-tool would automatically
detect an appropriate site for the new DC. However, it only did this if
the --server option wasn't specified. The new DC's site got
automatically updated as part of the finddc() work, however, this step
gets skipped if we already know the server DC to join to.
In other words, if Default-First-Site-Name doesn't exist and you specify
--server in the join, then you have to also specify --site manually,
otherwise the command fails. This is precisely what's happening in the
join_ldapcmp.sh test, now that the backupfromdc testenv no longer has the
Default-First-Site-Name present.
This patch adds a new find_dc_site() function which uses the same
net.finddc() API (except based on the server-address rather than
domain-name). Assigning DEFAULTSITE has been moved so that it only
gets done if finddc() can't determine the site.

The provision code already defines "Default-First-Site-Name" so we might
as well reuse it.
The join.py already uses a suitable default, so assigning the default in
the domain netcmd code is unnecessary.

Add a DCCloneContext subclass which will rename the DB objects as they
get cloned. This uses the drs_ReplicateRenamer class added to drs_utils
in an earlier patch. Where the drs_Replicate object currently gets
created has been split out into a simple new function, which we can then
override in the rename case.
The other important difference is overriding the provision step, so that
we use the new domain-DN/realm when setting up the initial SAM DB (and
smb.conf, secrets.ldb, etc).

For the clone-only case, we have been avoiding a block of code in the
DCJoinContext's __init__(). The main reason we do this is because the
netbios_name is None for clones, and this block of code tries to derive
a bunch of values based on the netbios_name (otherwise, a few lines into
this block, it tries to do NoneType.lower(), which Python doesn't like
very much).
This code is not particularly clone-specific - it is just never going to
work if the netbios_name is None. So we can change the conditional
check, which allows us to get rid of the clone_only flag.

Currently for DC clones, we create a regular DCJoinContext, se a
'clone_only' flag, and then make lots of special checks for this flag
throughout the code. Instead, we can use inheritance to create a
DCCloneContext sub-class, and put the specialization there.
This means we can remove all the 'clone_only' checks from the code. The
only 2 methods that really differ are do_join() and join_finalize(), and
these don't share much code at all. (To avoid duplication, I split the
first part of do_join() into a new build_nc_lists() function, but this
is a pretty trivial code move).
We still pass the clone_only flag into the __init__() as there's still
one case where we want to avoid doing work in the case of the clone.
For clarity, I'll refactor this in a subsequent patch.

This avoids issues getting replication going after the DC first starts
as the rest of the domain does not have to wait for samba_dnsupdate to
run successfully
We do not just run samba_dnsupdate as we want to strictly
operate against the DC we just joined:
- We do not want to query another DNS server
- We do not want to obtain a Kerberos ticket for the new DC
(as the KDC we select may not be the DC we just joined,
and so may not be in sync with the password we just set)
- We do not wish to set the _ldap records until we have started
- We do not wish to use NTLM (the --use-samba-tool mode forces
NTLM)
The downside to using DCE/RPC rather than DNS is that these will
be regarded as static entries, and (against windows) have a the ACL
assigned for static entries. However this is still better than no
DNS at all.
Because some tests want a DNS record matching their own name
this fixes some tests and removes entires from knownfail
