Replace operation removes the current data node configuration and sets
the provided value. As current northbound code works only with one
xpath at a time, the operation only makes sense to clear the config of
a container without deleting it itself. However, the next step is to
allow passing JSON-encoded complex values to northbound operations which
will make replace operation much more useful.

Currently, there's a single operation type which doesn't return error
if the object doesn't exists. To be compatible with NETCONF/RESTCONF,
we should support differentiate between DELETE (fails when object
doesn't exist) and REMOVE (doesn't fail if the object doesn't exist).

Currently, there's no difference between CREATE and MODIFY operations.
To be compatible with NETCONF/RESTCONF, add new CREATE_EXCL operation
that throws an error if the configuration data already exists.

Currently, nb_operation enum means two different things - edit operation
type (frontend part), and callback type (backend part). These types
overlap, but they are not identical. We need to add more operation
types to support NETCONF/RESTCONF integration, so it's better to have
separate enums to identify different entities.

The candidate yang tree should be validated before `nb_config_diff` is
called. `nb_config_diff` ignores all prohibited operations and can
provide an empty change list because of this. For example, if a user
deletes a mandatory node from the candidate datastore and tries to make
a commit, they'll receive the "No changes found to be committed!" error,
because such a change is ignored by `nb_config_diff`. Instead, mgmtd
should tell the user that their candidate datastore is not valid and
can't be commited.

Batch IDs are only used to verify that all messages were received and
processed by a backend. It's not necessary to do that as we use reliable
stream transport - messages can't be dropped or received out of order.
This commit also fixes possible race condition that can happen if
one backend process messages slower than other backends.

The code doesn't work at all. It tries to use libyang operation
metadata in a regular (not diff) data tree, and regular data trees
don't provide this data. Also, for destroy operations, it searches
for nodes in the running config, which may not have the deleted nodes
if we're not using implicit commits.

The lock/unlocks are being done short-circuit so they are never pending;
however, the handling of the unlock notification was always resuming the command
if pending was set. In all cases pending is set for another command. For example
implicit commit locks then when notified its done unlocks which was clearing the
set-config pending flag and resuming that command incorrectly.

Move away from things like "lock if not locked" type code, require the
user has locked prior to geting to that point.
For now we warn if we are taking a lock we already had; however, this
should really be a failure point.
New requirements:
SETCFG -
not implicit commit - requires user has locked candidate DS and they
must unlock after
implicit commit - requires user has locked candidate and running DS
both locks will be unlocked on reply to the SETCFG
COMMITCFG -
requires user has locked candidate and running DS and they must unlock
after
rollback - this code now get both locks and then does an unlock and
early return thing on the adapter side. It needs to be un-special
cased in follow up work that would also include tests for this
functionality.

I believe coverity can't tell the length of the return value from strftime based
on the format string (like we can), so it allows `n` to be larger than it could
be which then allows `sz - n` to be negative which is size_t positive and very
large so it thinks an overrun is possible.
