This has been noticed on several systems of mine, all 16.04.
Landscape Client takes up, over time, an *extreme* amount of system resources.
On a 1024MB RAM system, within 3 days to a month, Landscape Client and it's python scripts (possibly cached data?) are consuming massive quantities of memory - in the realm of 512MB RAM and over 400MB of the Swap on the system.
This is repeatably shown in other systems of mine as well. Is there a memory leak or something in landscape-client that would contribute to this issue?

[Impact]
* Memory usage of landscape processes abnormally grows, over time,
even for processes which are generally idle and have no reason to
grow.
* Most of that memory leak is due to uninitialized python-twisted
logging facilities buffering logs and their context. This fix
Initializes logging with a null handler to have those unused log
entries discarded.
* Upstream twisted has mitigated part of the issue in recent releases
by reducing the default buffer size. Because of that, the impact
of this bug is greater on xenial.
[Test Case]
* register a landscape client and log the memory growth over a day
* the effect is most noticeable on /usr/bin/landscape-client and less on
the other processes
* the memory difference on recent releases (bionic and up) is
expected to be smaller (~10mb on bionic instead of 200mb on xenial)
[Regression Potential]
* The fix initializes twisted logging, which is unused by landscape
so it is unlikely to have an impact.
* The fix comes from recommendations on the upstream bug:
https://twistedmatrix.com/trac/ticket/8164
