force replacement of link_name with a new sysmlink, if it existed
before the call.

Do "from . import log" instead of "from jwutils import log". It works
and looks cleaner than a module referencing itself. Not entirely sure
if that's the way to go, I must admit.

Commit 72d56d9 (Move type argument into config) swapped the order of
arguments in Auth.load(), but the ctor of ldap.Auth didn't follow the
change, fix that.
Signed-off-by: Jan Lindemann <jan@janware.com>
Auth.load() takes a "tp" argument, specifying the Auth module name to
load. In case of jw-devops, this is part of the configuration, which
is also passed as an argument. Make taking 'type' from the config the
default. Note that this changes the prototype.

ldap.Auth lost a lot of code when jwutils.ldap was introduced, and

WSGI doesn't like sys.exit() being called, so avoid it. Two cases
need to be taken into consideration:
1. No exception thrown by self.args.func()
The variable exit_status is zero, we can check that and _not_
call sys.exit()
2. Exception thrown by self.args.func()
In that case, the exception should be raised, to be caught by
WSGI / ASGI whatever to do what they want with it. The code
calling sys.exit() is never reached. Hence, we need to add
--backtrace to the invocation options.

add_argument() at the face of it looks much like
ArgumentParser.add_argument(), but is a function, not a class method.
It takes the ArgsContainer|ArgParser instance as first argument, then
decides what type it is, and proceeds to use this knowledge to decide
whether or not the argument to be added already has a definition.

Add functions log.(add|rm)_capture_stream(). The functions are meant

add_capture_stream() takes a currently unused flags argument, and it
suppresses everything else logged until the stream is removed again.
