- Basic implementation that allows to publish sensors as operations
of other sensors
- Still not functional and untested

- Using a hash ("#") in MQTT topics apparently crashes the mosquitto client

- Allows to perform system-wide smoothing using only one accumulator per sensor
- Basic functionality works, more thorough testing to follow
- Metadata updating functionality still to be implemented

Experimental status! Creates installable package, but actually installing it may break the system. For tests a disposable VM is recommended

Should not break CPU sensor instatiation anymore
Invalidates commit 1a5e05a7

-sends data as JSON to CollectAgent instead of storing in Cassandra directly
-adapt CA to support iob data

- Sensor/Group overwriting broke CPU sensor instantiation
- Looking for a more robust solution

- Prevented instantiating sensors from templates within template groups

Pusher SensorGroupTemplate: Also replace partial template specialization with derived SensorGroupTemplate for entities

Pusher: Refactor ConfiguratorTemplate once again. Replace partial template specialization with derived ConfiguratorTemplate for entities

- This allows to use additional features in the plugin, e.g. templates
for single sensors

- The interval field now defaults to the value inherited from the
sensor groups that the sensor belongs to
- Metadata blocks in templates can now be overwritten completely or
only in part

setting publish to false for sensors which get aggregated to another sensor (they shouldn't be published).

- Default C++ to_string implementation only supplies 6 decimal digits of
accuracy, truncating very small scaling factors
- Now using string streams

Implementing more cache info to avoid doing excesive job updates. Implementing all ratio metrics. Renaming some metrics which were missleading

Fixing issue with connection details and template for the persystsql operator. Updating examples of config files.
