Actually not bumping the jsonrpc version which in theory is a violation,
however, the largest part of this has been gone already with the bump to
7.0 and no known client applications are using this anways any more.
This moves all the things and rules logic away from NymeaCore
into their respective modules where it belongs.
One major change is the removal of the removePolicy functionality.
This was somewhat broken as it was only working for rules but not
for all the other modules like scripts, experiences etc. After
an attempt to create something that works with all modules it
really seemed that this does not make a lot of sence after all,
given that updating rules would in most cases leave something
very broken behind and removing them was the only sane thing to do.
On the other hand, experience plugins may not work well with such
a policy eithre as they may require to do their own special thing.
So in the end the removePolicy was dropped altogether. Apps should
instead figure out themselves what removal of a thing may imply and
inform the user about that beforehand.
This ties those namespaces to the things permissions but won't
allow having different tags/appdata per user, which arguably would
be desirable. However, that's currently not that straight forward
to do, as at the moment there is no way to direct jsonrpc notifications
to a single user.
Some plugins may support network discovery, but may not be able to clearly
identify a device and return a list of discovery results that may
be the device, but also may not. As this breaks some app flows they
will be marked as "weak" discovery and can be excluded from said setup
wizards.
NOTE: This commit does not bump the API version even though it should
to avoid merge conflicts with other branches that do bump the version.
